Nagisa x Reader: Nagisa's Crush

"Did you say something?" Nagisa asks as he walks up to you. He acted as if the whole gender mishap didn't happen. All you can do is shake your head frantically. Nagisa suspiciously cocks his head, and gets closer you. The red in your cheeks deepens. Now that you knew Nagisa was a boy, it was hard to stay calm with him around. "You're all red. Do you have a fever?" Nagisa leans in and puts his hand on your forehead, which only enhanced the redness and heat in your face.

"I-I'm fine!" You find the strength to push Nagisa away, only to hear a loud crashing sound. When you look up, you find that you had pushed Nagisa into a shelf of empty beakers, causing him to bleed a bit from the broken glass. You let out a little gasp and rushed over to the poor boy. "I'm so sorry...!! It was just a reflex..." You sputter uncontrollably. It was then when Koro-sensei finally turned around.

"Oh! Nagisa, are you alright?" He started to pick him up with ease using those rather strange tentacles. You found it weird that it was just now that the octopus noticed the commotion. Did he not hear you yelling when you found out Nagisa's true gender? But there was no time for that, you tell yourself, as you try to wipe the blood off of him with part of your uniform shirt.

"Why don't you take him to the infirmary while we clean up here. I don't know what happened, but I'm sure you kids will solve it together." Koro-sensei tells you, patting your head with a wiggly tentacle.

"Wait, we have an infirmary?" One of the students asks as if it was the strangest, most bizarre thing ever. "Do we even have a nurse?" Another student added in.

You shudder at the feeling of Koro-sensei petting you in such a way, but nod in response.

In the rather crappy infirmary, Nagisa lay in the stiff bed as you carefully bandage him up. There was no nurse, and you barely even called this an infirmary. It was just a dingy room with a cabinet of cheap medical supplies and a stiff cot. It's usually what to expect for Class E.

"I didn't mean to push you that hard... I never wanted to hurt you..." You apologize solemnly. Nagisa turns on his side and gives you a weak smile.

"It's alright. Maybe your strength will come in handy in an assassination attempt. And I promise you, I'm fine." He says. You were surprised on how easily he could talk about assassination when he was in such pain. Your breathing grew heavy with guilt, and you couldn't bare to look at him any longer. Trying to avoid eye contact, you look down and grip the hem of your uniform skirt.

"Hey..." Nagisa gently reaches out and tips your chin up with his hand. He gives you an impish, yet cheerful and sincere smile, "If I can't take on this much, how can I ever expect to kill our teacher?" He asked. You couldn't help but smile back at him. There was the slightest bit of bloodlust in his eyes, but it was hard to tell.

You spend a little more time taking care of Nagisa's injuries when you suddenly start to yawn a bit. You try to brush off your sleepiness and continue but Nagisa grabs your wrist.

"Are you tired?" Nagisa asked, pulling at your hand. He slowly scooted over on the cot to make more room, "Wanna sleep with me?" He asked as if it was the most normal thing in the world.

"W-w-what?! B-but you... And I...." You kept fumbling over your words, feeling your cheeks getting hot again. Nagisa couldn't help but let out a small chuckle.

"If you still thought I was a girl, you'd probably do it." He remarked. You blush even harder. It was actually true. If you still thought Nagisa was a female, it would've been no problem. But since he was a boy, getting into bed with him wasn't as easy.

"B-but you're not a girl!" You protest. Nonetheless, Nagisa didn't let go of your hand. In fact, he pulled on you so hard that you fell right on top of him on the cot. At this unexpected surprise, Nagisa started to blush as well.
