When you know, you know

When you know, you know

It kinda makes me laugh, runnin' down that path

When you're good as gold

'Cause when you know, you know



 

Sunoo’s livestream kicked off with the familiar cheerful jingle — a soft melody that always made his regular viewers feel like they were stepping into a cozy corner of the internet. 

The screen faded in from black to warm lighting, golden and comforting, casting a soft glow across his bedroom. Fairy lights twinkled lazily along the edges of his shelves, and a plushie peeked out from behind a stack of skincare bottles. 

His mic stand was tilted slightly, a telltale sign that he had been adjusting it last minute — and sure enough, the first thing viewers saw was Sunoo leaning in with both hands gripping the webcam gently, adjusting the angle with practiced ease.

His tongue stuck out in focused concentration, hoodie sleeves tugged over his palms as he shifted the camera just right. When he finally settled back into frame, the hoodie slipped a bit off one shoulder, and he made no move to fix it. He gave a bright wave, dimples peeking out as his eyes lit up.

“Hi, everyone!” he greeted, voice warm and energetic, as if the entire chat were made up of close friends.

“Welcome back to another live — but today’s a little different.” He leaned forward slightly, elbows resting on the desk, and tilted his head at the camera with a knowing little smile. 

“I know you’ve all been... very persistent lately.”

The chat immediately flooded with emojis, hearts, and teasing comments. Sunoo let out a breathy laugh, eyes scanning the chaos.

“Yeah, yeah, I saw the clips,” he said, rubbing the back of his neck with a mock-sheepish grin. 

“I guess there’s no hiding it anymore, huh?”

He clicked something offscreen and leaned back again, fingers lacing together as he smiled, softer this time.

“Ever since a certain someone got a little too comfortable on camera last week — and may or may not have accidentally revealed we’ve been dating for a year — I’ve been getting nonstop messages. I swear, I’ve never seen chat move that fast in my life.”

He paused for dramatic effect, letting the anticipation build as the comment section went wild again. Someone typed in all caps:

“DROP THE BOYFRIEND STREAM!!!”

“WHERE IS THE ICE PRINCE”

“IS SUNGHOON COMING TO THE STREAM”

“IS HE THERE RN 👀”

Sunoo covered his mouth to stifle a giggle. 

“Okay, okay. I hear you. I know you want a livestream with him. And you know what?” 

He shifted in his seat, reaching for his drink — a glass with lemon slices floating in sparkling water — and took a sip before continuing, voice casual but fond.

“He’s actually home right now. Just got back from practice, I think. I haven’t asked him yet if he wants to come on stream with me tonight, so I might need you all to be on your best behavior—well. As best as you can be.”

The hoodie sleeve slipped again, and he tugged it back up absentmindedly as he glanced toward the hallway beyond his open door. 

The faint sound of a closet door creaking and muffled footsteps could be heard through his mic. 

He gave the camera a look. 

“No promises, but if he’s not too tired… maybe.”

The chat went feral again, but Sunoo only smiled, chin resting on his hand now, soft and glowing in the evening light. 

The moment felt quiet for a second — personal, even. He wasn’t just a streamer entertaining fans. He was someone in love, and his whole face showed it.

“Anyway,” he said after a beat, straightening up with a playful grin. 

“Let’s just see how it goes. But don’t say I didn’t warn you. He’s a little shy on camera when it’s not accidental.”

With that, Sunoo stood up and padded out of the streaming room, leaving the camera rolling on the softly lit desk and makeup neatly arranged in front of it. 

A moment later, his voice could be faintly heard from the hallway. “Hoonie? Do you wanna—well, only if you’re okay with it—maybe join me on stream today? Just for a little bit? You can do my makeup and help answer some questions.”  

There was a short pause, whisper of words, then a gentle hum of agreement, low and warm. 

“Yeah?” Sunoo’s voice perked up, clearly delighted. 

“Okay! Just come in whenever you’re ready. I’ll go ahead and get things started.” 

The door creaked open again, and Sunoo slipped back into his seat, cheeks a little pink as he adjusted his mic with a smile.

“Yes, I’ve seen the ‘boyfriend does your makeup’ challenge tags,” Sunoo continued with a mock sigh, scrolling through the chat with his fingers tapping against the desk. 

“Every. Single. Time. You guys do not give up.”

The chat responded with a flood of hearts, "FINALLYs", and a few suspiciously smug “WE KNEW IT”, “I’M SO HAPPY I’M WATCHING THIS LIVE”, “OHMYGOD IT’S HAPPENING, IT’S HAPPENING” messages.

“So today,” he said, raising a brow and letting his voice drop into a faux-dramatic tone, “I bring you a very special guest. He said he’d join after he showers and looks ‘decent enough for the camera,’ whatever that means.”

From somewhere in the apartment, a faint “I heard that!” echoed, slightly muffled by a closing bathroom door. Sunoo bit back a grin and leaned closer to the mic.

“He’s probably fixing his hair,” he stage-whispered to the chat. “Like it isn’t always perfect anyway.”

Sunoo took a moment to tidy up the space behind him, pushing aside the tinted lip balms and his little mirror set while humming softly to himself. 

“So today’s stream is a little mix of things,” he explained, fingers tapping the product lineup beside him. 

“We’re doing a review of some of the new spring makeup releases — and yes, yes, before you ask, I did save one unopened for him to use. I trust him. Mostly.”

As if on cue, there was some soft shuffling just off camera — a pair of socked feet coming into view first, then the rest of Park Sunghoon, freshly showered and comfortable in a pale grey hoodie and sweatpants. 

His hair was still slightly damp at the ends, soft and pushed back like he had tried (and failed) not to care too much about it.

He paused near the edge of the frame, eyes flicking nervously toward Sunoo.

“Come here,” Sunoo coaxed, reaching out a hand without looking. Sunghoon took it instantly, and let himself be pulled into view.

And just like that, chaos.

The chat erupted. Messages flew up faster than Sunoo could process. 

Strings of emojis, excited keysmashes, declarations of “THEY’RE SO CUTE I CAN’T BREATHE,” and of course, plenty of people zooming in on how Sunghoon’s fingers naturally laced with Sunoo’s.

“This,” Sunoo said, beaming, his cheeks round with a smile that crinkled his eyes, “is my boyfriend, Sunghoon.”

Sunghoon gave a small, sheepish wave, his thumb nervously brushing over the back of Sunoo’s hand. 

“Hi,” he said, a little awkward but clearly trying. “Um, I’m Sunghoon. I do figure skating… and now, apparently, makeup.”

The chat flew so fast the stream lagged for a half second.

“I thought I’d have to beg him to do this,” Sunoo teased, his shoulder nudging Sunghoon’s. “But he kept on nodding before I even finished the question.”

Sunghoon chuckled. “I always wanted to try doing your makeup. You always look so pretty… so I figured, why not contribute to the art.”

“Flirting already?” Sunoo said, tilting his head and leaning closer. “We haven’t even started.”

Sunghoon grinned, a bit more relaxed now. “Just being honest.”

Then he turned to the camera and added, “I also do photography as a hobby, I like cooking—”

“He’s lying,” Sunoo cut in with a playful glare. “He’s only cooked pasta and braised beef.”

“Okay, trying to cook,” Sunghoon corrected with an offended pout. “And Sunoo—my very talented, very beautiful boyfriend—lives off fruit snacks and chocolates, so I think we’re even.”

“I do not live off fruit snacks!”

Sunghoon gave the camera a pointed look. “The pantry disagrees.”

Sunoo whined dramatically and tried to swat at him, but Sunghoon ducked behind the palette on the table. 

“Anyway,” he said from behind the cardboard box like it was a shield, “Today, I’m doing his makeup. And I’m very nervous because if I mess up, you’re all going to know.”

“You’ll do great,” Sunoo said softly, reaching to squeeze his hand again. “I trust you.”

The sincerity in Sunoo’s voice made Sunghoon pause for a moment, eyes darting to his face. 

A beat passed between them, unspoken but warm, and then Sunghoon cleared his throat and reached for a product with mock confidence.

“All right. Step one. This one’s called… Hydrating Glow Mist.” He sprayed it directly at Sunoo without warning.

Sunghoon! ” Sunoo squeaked, face scrunching up, while the chat lost its collective mind.

“Okay, okay! I’ll be serious!” Sunghoon laughed, dabbing at Sunoo’s cheeks with a sponge. “You’re just cute when you get flustered.”

Sunoo gave him a betrayed look, but he was already smiling again.

They brought the camera closer and spread the makeup products out between them on the bed. Sunghoon looked over the brushes and palettes like he was studying a foreign language.

“Okay,” he said with a breath. “Primer… first?”

“You got it.” Sunoo leaned forward obediently.

Sunghoon pumped a tiny amount onto his hand, then dabbed it onto Sunoo’s face like he was handling the world’s most fragile object.

“Am I supposed to press it in?” Sunghoon asked, brows furrowed.

“Not slap it in, but yeah,” Sunoo replied, lips twitching with amusement. “You’re barely touching me.”

Sunghoon’s fingers ghosted across his cheeks. “I don’t want to poke your eye out or ruin your skin or something.”

“You won’t,” Sunoo said gently. “It’s me, remember? You can’t mess me up.”

That made Sunghoon pause. His face softened, eyes flicking up to Sunoo’s. 

The room felt still for a moment — like even the live chat had quieted — before Sunghoon leaned in and kissed his forehead.

“Okay,” he murmured. “Next.”

He moved to check what the other products are, each step taken with so much care it was laughable. He’d hesitate before each touch, brush hovering in the air like he needed permission.

“Still not touching my face,” Sunoo teased again.

“I don’t want to poke you!”

“You’re not doing surgery.”

“Still,” Sunghoon said, sweeping a bit of the liquid across Sunoo’s cheek — finally applying some actual pressure. “You’re too pretty to mess up.”

Sunoo’s cheeks were already flushed, but not from the makeup.

Sunghoon stepped back to admire his handiwork, then leaned in and kissed the tip of Sunoo’s nose. Then his cheek. Then another kiss to his temple.

“Sunghoon,” Sunoo said, voice low. “We’re live.”

Sunghoon froze, eyes wide. “Oh.”

He blinked. Then laughed — that bright, boyish laugh that only came out when he was flustered. “Oops.”

He gave the camera an apologetic smile, complete with his signature eye crinkle. “Sorry. Forgot for a second.”

A second? ” Sunoo asked, laughing now too.

“Maybe… two. Or three. You’re distracting.”

Sunoo rolled his eyes, but his smile was soft. “Should’ve titled this ‘boyfriend forgets there’s a livestream and kisses me instead.’”

“Better title anyway,” Sunghoon mumbled, still stealing a small kiss at the corner of Sunoo’s lips before turning back to the makeup like nothing happened.

As Sunghoon carefully applied product, the Q&A part of the stream began. Sunoo read out questions from chat, most of them harmlessly curious or downright chaotic.

“Who said ‘I love you’ first?”

Sunghoon hesitated, carefully dabbing cushion foundation onto Sunoo’s cheek. “Me. But he said it louder.”

Sunoo blushed, nose scrunching. “He said it when we were watching a movie and thought I fell asleep. It was really soft and sweet. But I was awake. So I said it back and he freaked out.”

“I didn’t freak out,” Sunghoon said, clearing his throat. “I just—paused the movie and stared at him for, like, a full minute.”

“You did. You looked like you were buffering.”

The chat exploded with laughter and sun emojis. Sunghoon fought a smile as he moved on to concealer, mumbling, “Keep still or I’ll give you anime under-eyes.”

“What’s the most annoying thing about each other?” Sunoo read next.

Sunghoon didn’t even need to think. “He leaves empty fruit snack wrappers in every corner of the apartment. I found one inside the blanket.”

“I can’t help it if I snack while I’m cozy!” Sunoo said defensively. “And you—you steal the covers at night.”

“I run cold!”

“I run colder!”

They bantered like that for a while, the kind of gentle teasing only couples fully used to each other can manage. Sunghoon leaned in with a careful hand to blend Sunoo’s blush while the latter glanced back down at the chat.

“Oooh,” Sunoo hummed, “someone asked if we play games together. The answer is yes, but he gets competitive.”

“I do not,” Sunghoon said, sounding almost offended as he uncapped the eyeliner pen with way too much confidence.

“You rage quit Uno.”

“That game’s rigged. You played a draw four and smiled while doing it. I knew what kind of person you were in that moment.”

“I’m a winner,” Sunoo grinned.

“And I’m struggling with this eyeliner,” Sunghoon muttered, trying to concentrate. “How do you do this every day? I feel like I’m defusing a bomb.”

Another comment caught Sunoo’s attention. He read it out loud with a giggle. “Is Sunghoon okay with horror?”

Sunghoon froze. “Absolutely not.”

“He screams louder than me,” Sunoo whispered into the mic.

Sunghoon looked at the camera, betrayed. “I don’t think so! And I’m not ashamed of my survival instincts.”

“He made us stop playing a horror game thirty minutes in because there was a hallway that ‘looked like it had a bad vibe.’”

“That hallway did have a bad vibe!”

Sunoo leaned into him, cheeks lifted in amusement, and patted his knee. “It’s okay, baby. I’ll protect you.”

Sunghoon let out a long sigh and nudged his chin. “Stop moving or I’ll contour your ears.”

Sunoo laughed but sat still, reading another question from the now absolutely feral chat. “What do you think when I shout during streams?”

“Oh.” Sunghoon blinked. “You mean like last week when you screamed because your team lost and I dropped my coffee?”

Sunoo winced. “Oops?”

“It’s fine,” Sunghoon said, smiling softly. “I like hearing you have fun. Even when you’re loud. And when I’m not home, it’s kind of comforting, actually. Makes the place feel less quiet.”

Sunoo glanced at him, a little surprised, eyes softening. “That’s so sweet…”

Sunghoon just nudged him gently and cleared his throat. “Don’t get all emotional. I’m trying to do your eyebrows.”

“You’re doing them too high!”

“I’m giving you a lifted look.”

“What even is that? And I want to look soft, not like I’m judging everyone in the room!”

“But baby, you are judging everyone in the room.”

Another burst of laughter echoed in the chat. Sunoo barely managed to get out the next question through his grin. “Okay, okay. Someone asked: Do you ever fight?”

Sunghoon slowed down, brushing a spoolie through Sunoo’s brows before answering. “Not really big fights. But sometimes we get quiet. Like if one of us is overwhelmed. Or tired.”

Sunoo nodded. “We’ve gotten better at talking, though. Or giving space when the other needs it.”

“And we always say sorry,” Sunghoon added. “Even if it’s small. I like that about us.”

Sunoo squeezed his hand under the table. “Me too.”

The chat had shifted to soft hearts and a flood of “relationship goals” comments. 

But Sunoo didn’t even glance at the screen. He was watching Sunghoon focus now, tongue peeking out slightly as he carefully applied a soft pink lip tint.

“You’re really taking this seriously,” Sunoo teased, voice quiet.

“I want you to look good,” Sunghoon said, smiling without looking up. “You always do.”

“Flatterer,” Sunoo whispered.

“You like it.”

“I do.”

There was a beat of silence while Sunghoon set down the tint and inspected his work. “Okay. Done. I think. Don’t roast me.”

Sunoo turned to the camera dramatically. “Chat, prepare yourselves. This is Park Sunghoon’s official makeup debut.”

He turned his head from side to side, letting the lighting hit his skin. 

The base was clean, the blush soft and peachy, and the lips perfectly dabbed. It was clear Sunghoon had paid close attention, even if he tried to play it off casually.

The chat went wild.

“You look…” Sunghoon hesitated, staring at him with a slightly dazed expression. “Really pretty.”

Sunoo’s smile turned shy. “You did great, Hoon.”

Sunghoon leaned over and pressed a kiss to his cheek, quick and gentle. “Next time, you do mine.”

“I’ll go all out.”

“I’m scared.”

“You should be.”

They laughed together, leaning into each other, comfortable and glowing in the golden lighting of the streaming room. 

For a while, they just read more questions and gave silly answers. 

Favorite snack to share? Pocky. Favorite cuddle position? “Me starfishing and him stuck to my side,” Sunoo said proudly. Dream vacation? “Anywhere without Wi-Fi,” Sunghoon answered, only to get smacked lightly with a blush brush.

Eventually, Sunoo leaned back and smiled at the camera, eyes glowing. “Thank you for being so kind to us. This was really fun. And special.”

Sunghoon nodded. “Thanks for not roasting me too hard.”

“You guys were really sweet,” Sunoo agreed. “Maybe next time, we’ll do a baking stream. You know… if he doesn’t burn the kitchen down.”

“No promises,” Sunghoon grinned.

“Okay, say bye now, Hoonie,” Sunoo teased.

Sunghoon waved sheepishly. “Bye, everyone.”

As the stream faded out to its closing jingle, Sunghoon leaned closer again and whispered, just off-mic, “You’re still the prettiest thing I’ve ever seen.”

Sunoo, already reaching to end the stream, missed the button and just smiled down at his lap for a few seconds, eyes crinkling with happiness.

And chat? Lost. Their. Minds.
