Work Text:
Izuku was carefully making his way up to Setsuna Tokage's room in the 1-B dorms. Why? She had gotten sick from the cold weather. And since everybody else was outside, Izuku volunteered to make sure she was okay. That included ferrying trays of tissue boxes and chicken noodle bowls up and down the floors.
Before this mess, they became a couple after sharing their New Year's kiss, and were inseparable. No one actually knew they were dating except Bakugou. Mina would always try and conspire about why the two were close, although Izuku shot her down every time. They were more just really close friends that liked to cuddle and look absolutely adorable together. They hadn't actually kissed since New Year's because Midoriya would always fall near unconsciousness whenever Setsuna tried to kiss him. Monoma made it very clear that he wanted to kill Izuku, although Kendo made it a point to put her hand around his neck when both of the boys were in the same room.
"Thank you, really for volunteering for this, Izuku. Your efforts are appreciated." Kan-sensei spoke up as they walked him to her room. Aizawa was with the both of them as well, who just hummed in agreement while looking away.
As they reached her room, they opened the door. It was Dinosaur themed, much like how Izuku's was All Might themes, although to a much lesser extent. On the bed were about three separate blankets, one of them a heat controlled one. In the middle, there was a lump and a mop of curly green hair that was laying off to the side, covering the person's face. In the room itself, it was just below sweltering. Izuku panted a little as he entered just from the heat alone. The lump in the bed shuffled a little bit and groaned, before turning over. She blew her hair out of her eyes, revealing her beautiful face, and then just stared. Izuku carefully set the tray down next to her bed and then sat in a folding chair beside her bed. Aizawa and Kan-sensei stood behind him. Setsuna sat up shakily, grumbled a thank you, and took one of the tissue boxes to blow her nose before tossing it into the trash can nearby.
"Well, guess we'll leave you." Kan said as he shuffled out of the door. Aizawa stood there still, before speaking up.
"Midoriya, I need to speak with you." He said, bored, gesturing towards the door. Izuku got up nervously and walked out with him. Aizawa made sure to shut the door before turning.
"You do know what you're getting yourself into, right Problem Child?" He asked. Midoriya just nodded.
"Yes. It's my job to make sure she's okay while everybody else is outside." He said while looking out of the hallway window as Mineta got destroyed by a volley of snowballs by the girls from both classes. Aizawa just rolled his eyes and sighed, pinching the bridge of his nose in frustration.
"Fine. If you get sick, don't come crying to me about not being able to go outside and fuck around." Aizawa warned before turning to the door and opening it. Setsuna had sank back down into the bed, this time however with the covers pulled off of most of her body. Izuku cautiously sat back down, while Aizawa stood back, almost as if he knew what was going to happen.
Suddenly, two detached hands grabbed Izuku's right arm and pulled him over Setsuna's bed. She then grabbed him and pulled him down, before climbing on top of him with the blankets. Izuku tried moving away, but Setsuna had a vice grip and pulled him back before resting her head on his chest. Izuku's mind spun out completely. Out of everything, that was about the last thing he expected. Then he realized that she was only in her underwear, a violet bra and panties. He felt a rising sensation in his pants, but forced it down the best he could. 'Pleasedon'tmakethingsweirdple-' He thought frantically. Oh well, biology is biology, it was going to happen anyway.
Aizawa quickly became uncomfortable, and made it to the door. As he was about to close it, he made one final announcement in his usual bored and monotone voice.
"Kan told me she would try to do that. Apparently it's normal and she let's go around, mmh, an hour or two, maybe. Anyway, goodbye you little shits." And with that, he shut the door and quickly made his escape.
There Izuku was, alone, stranded in a room with a girl with the flu who might kill him if he moved. He honestly doesn't know why he's surprised. He'd heard that when she gets sick, she becomes partially insane. She buries herself in blankets and doesn't move for hours on end, she has extremely weird eating patterns, her tongue turns blue, and that she also latches onto any sort of heat source while muttering something about, "The warmth." 'Maybe that's why Kan-sensei and Aizawa-sensei were keeping their distance?' He thought to himself. Izuku had to do something. He couldn't just lay here. Or maybe he could.
"Tokage, please, I need to get up." Izuku said firmly. He was trying to get up to leave to put the tray back downstairs. However, Setsuna let out a whimper and held on to his hand. Then Izuku noticed the pained expression in her eyes like she was about to cry. Then it hit him. She was in a moment of weakness and barely could move, she needed comfort, that being in the form of Izuku himself. Izuku just sighed and lowered his shoulders. 'I can't leave her like this. Damn you, heroic instincts.'
"Come here." Izuku said as he got back onto the bed and hugged Setsuna before laying down. She hugged back as she moved herself on top of him again and forced her face into his chest again. She let out a few silent sobs as she began letting out tremors from her body. She was crying. Izuku's heroic instincts took over again and began rubbing her back as he whispered softly in her ear in an attempt to get her to stop crying.
"M-My h-head..." She let out weakly. 'Oh, so that's why.' Izuku thought to himself. Migraines while your sick are an extremely nasty thing to even think about. Eventually, her breathing evened out and she stopped moving. She cried herself to sleep. 'I can't take anymore of seeing her like this. It's too sad.' He thought. He continued rubbing her back to comfort her. As he did he began thinking. It felt... relaxing. Having Setsuna cling to him made him calm down after his initial shock. Sure, he might get sick from it, but this was worth it. Sure, it happened on Christmas Eve, but it didn't make it any less surprising. Holding her tight like this under three separate blankets was one of the most comfortable things he'd ever felt.
He gave her a small kiss on the forehead and snuggled her closer before letting the dream world pull him into sleep with her.

Aizawa and Kan were currently in the teachers lounge, getting ready to go back out and organize a snowball fight between the classes.
"So, did you tell Midoriya about Tokage being clingy to people when she's sick?" Kan asked as he looked up.
"After she grabbed him and pinned him to the bed, yeah." Aizawa said as he took a sip of his coffee. Kan just chuckled as he turned back to getting his boots back on.
----------------------------------------------------------------------------------------------------------------------------------------------------
Izuku woke back up. It felt like he had just taken a small nap, yet felt as if slept a whole day. Surprisingly, he didn't feel sick at all. He remembered where he was, and smiled a bit. He went to go grab his phone to check the time, but felt it held back. He looked down, and found that Setsuna had wrapped both of them tightly in the heated blanket and set it on to high, with the other blankets wrapped over it. Setsuna was still laying on his chest, snoring softly with a peaceful look on her face. Her arms had wound themselves around his torso, and her legs ran along Izuku's, only stopping because she was shorter.
Izuku managed to wriggle his left arm out and over to the desk where the phone was and looked at the time. 9:40. It was 7:40 when he got here. They'd been snuggling for that long. He laughed under his breath before putting his phone back down and pulled his arm back into the mess of blankets. That's when he noticed Setsuna stir a bit before calming back down. He then weirdly noticed how nice her figure was, a blush slowly creeping up his face. 'Stop it you pervert. Just because she's your girlfriend doesn't mean it's appropriate.' Then he remembered that she was only dressed in her violet-colored underwear. If he wasn't red before, he certainly was now. 'Oh God, I don't want to become Mineta...'He groaned internally. He just went back to massaging her back and arms to soothe her, trying ignore he fact she was practically naked.
Then he heard a yawn, and looked down again. Emerald green eyes fluttered open and stared back at Izuku's. She kissed him on his chest and struggled to move her arms out from where they were resting because of how tight the blankets were. Izuku just chuckled and began helping her, giving her enough room to get her arms up. When she did, she smiled at him and pulled him into a hug before kissing him on the lips, which he happily reciprocated.
"Good morning, Izu-kun..." She said softly, her smile widening. Izuku reciprocated it with a smile of his own.
"Morning. Do you feel any better?" Izuku asked, to which Setsuna nodded, yawning.
"Yeah. I actually don't feel sick anymore, surprisingly. All thanks to you." She said while grinning. Izuku blushed before wrapping his girlfriend into another hug.
"So, uhhhh, what do you want to do? It's only 9:40 yet." Izuku asked.
"Mmmmh, I dunno, stay here and cuddle some more." She said as she stretched her arms up. It was here where her chest was perfectly visible, making Izuku flush red again. She seemed to notice this and had a devilish smirk creep up her face. She slowly got out of bed, stumbling slightly before standing up and stretching some more, her smirk still present.
"What? Don't like my body?" She teased.
"N-No! I-It's J-just... I-I S-Still Haven't G-Gotten used t-to it y-yet..." He stammered. Setsuna snorted in response.
"Aww, you're so adorable. You're welcome to look if you like." She teased some more, putting her hands on her hips while she stretched down. Izuku looked away again in embarrassment. He stole a quick glance and saw just how gorgeous she looked. He looked away again, although a lot slower this time.
"You know I can tell you're looking right?" Setsuna asked while looking up at him.
"S-Sorry..." He mumbled.
"I said you're welcome to look. Here, I'll give a closeup." Setsuna said, her grin widening even more.
"Hu-" Izuku didn't even have time to finish before Setsuna sat herself down right in front of him, plopping down on his legs before pulling the blankets over her back. Then she leaned forward towards Izuku, who was evidently shaking, and pulled his shirt off.
"Listen, we've known each other for a while, and we're dating. There's nothing weird about looking, and for taking care of me, this is your reward." She said softly as she kissed him on the lips again. Izuku hesitated for a second.
"A-Are you s-sure?" He asked.
"Yes, I'm sure, now come make out with me!" Setsuna ordered, pulling the blankets around both of them.
"Y-Yes Ma'am..." Izuku said. Setsuna giggled before kissing him back and wrapping her arms around him. Izuku wasted no time reciprocating it and wrapping both of them in the blankets before the make out session went fully underway.
Needless to say, both were in pure bliss when they eventually got up.
