"Shun, I already told you that I think this is enough." Aren says, trying to calm his best friend down as the said teen was obsessively fiddling with the cake that they bought.
"But I want it to be perfect - like, I know Kusuo wouldn't have any problems with it but-" Shun starts, but the purple haired teen shushes him up.
"If you don't stop now-" Aren places both his hands on the bluenette's shoulders and looks him in the eye. "-You'll definitely somehow end up talking yourself into breaking up with Kusuo."
"...You're right.” Shun agrees, taking a deep breath and stepping away from the white cake with simple, but elegant writing on it that read ‘ Happy Birthday, Kusuo! ’- the cake itself wasn't really the star of the show, because the important thing was the pedestal cake topper that had Shun's special coffee jelly.
(If you're asking why it's special, the TLDR is that this was the specific coffee jelly that had Kusuo re-thinking everything about Shun.)
“And besides, we’re all acting as if Kusuo hasn’t already guessed what we were planning today.” Kusuo’s father, Kuniharu, chimes in, a pensive look on his face and the two teens mirror the expression. The three of them all sit in silence for a bit, letting it fester in the air before Kuniharu finally snaps out of it and ushers the two get dressed.
Shun and Aren look at each other, sharing a laugh when they realized that they were still practically in their sleep attire because they were at Kusuo's house the moment that the psychic and his mom left to start the diversion (Read: 8 AM). The two teens head to Kusuo's bedroom, rummaging through their bags to look for the party clothes they brought, and Aren burst out laughing when he saw Shun pull out a fishnet top along with a choker that had two lines of chains attached to it. The bluenette glares at him.
"Are you planning on gifting yourself to Kusuo? Oh, and wait, let me guess: you're planning on wearing a crop top, the white one with a skull on it, on top of the fishnet one?" Aren says, laughing even harder when Shun takes out the said article of clothing from his bag with shame written on his face. "Kusuo is… definitely gonna have a feast." The purple haired teen jokes one last time before letting it go, in fear that if Shun's face gets any redder the bluenette might explode.
The two take turns changing in the bathroom of Kusuo's room before finally heading down to where Kusuo's dad has finished ' decorating '; Shun wouldn't really call it decorations if it was two number balloons (20), but he did have to consider that if they actually went the legitimate decorating route then Kusuo's eyes would hurt if there was too much going on.
Kuniharu turns to them, smiling happily and complimenting them on what they were wearing before his expression changes as if he just realized something. "Ah, Shun… You and Kusuo are gonna head back to his apartment later tonight, right?" He asks cautiously, as if he was trying to gauge something. Shun burned a bright red while Aren tried his best, and is failing, to not laugh his ass off at the situation.
Shun was about to answer, but before he can even open his mouth, they suddenly hear the door knob jiggling. This was their cue, with Aren and Shun carefully holding the cake and Kusuo's dad holding the lighter for the candle. The three of them start singing ' Happy Birthday ' to the psychic the moment he and his mother come through the door; Shun was worried that his boyfriend would just look barely amused, but a wide smile spreads across his face when he sees Kusuo with a look of genuine shock.
"Thanks, everyone." Kusuo says simply, but the smile on his face is the only thing the family needs to see to know that he appreciates what they did.
They do the normal birthday traditions; Cake smearing, candle blowing, pictures, and gift giving. Kusuo had a smile on his face the entire time, keeping Shun close to his side and an arm always loosely placed on the bluenette's waist; His parents awkwardly try to ignore the psychic's subtle possessiveness while Aren, on the other hand, kept making overly suggestive faces at Shun to get a reaction out of him since he found it incredibly funny.
Shun takes a deep breath. He should stop thinking about everything too much, because the look on his boyfriend’s face of genuine shock earlier just filled his heart with more adornment. He doesn’t need any more confirmation that everything was enough.
"Hey, Ku~ are you and Shun going back to your apartment after celebrating?" This time, it's Kurumi who asks with the same awkward smile that Kuniharu had earlier, which makes Shun burn a bright red as Aren shamelessly laughs. Kusuo doesn't understand what's so funny, but he doesn't question it and just nods; He had plans for an extra celebration.
