Unable to leave you (Nagisa x reader)

Season 2 part 3

The next day at school

"Sorry Koro Sensei!" I said as I ran into the the class room. When I got in everyone looked at me. "So you're okay huh?" Said Takebayashi as he adjusted his glasses. "Yeah......why?" I said as I glance at Takebayashi. "If you haven't notice (y/n) Nagisa isn't in class right now, but his stuff is still here" said Koro Sensei. I glanced to where Nagisa is supposed to sit, and I realized that Koro Sensei was right. "Why isn't he there" I asked as I faced Koro Sensei. Suddenly the door slides open, and Karasuma came into the class room dragging a person into the classroom by the hood. "LET GO OF ME! OR ELSE IM GOING TO KILL YOU!" Shouted the person. I quickly realized the person was Nagisa. "NAGISA! ARE YOU OKAY?!" I yelled as I ran over to him when Karasuma dropped him on the ground. When I touched his body it felt like he was made out of literal ice. "Let me go.....I need to know if she's okay......" said Nagisa as he passed out from the cold. "N-Nagisa......?" I studdered as tears went down my face. "It's okay (y/n) he's fine, we'll just warm him up" said Koro Sensei but I didn't reply. "..........it's all my fault.."I whispered as I placed my head onto his chest.

Later

After we ate I looked at Nagisa, he felt warmer but he still won't wake up. Suddenly someone pushed me and I fell onto Nagisa's body. ".....I need to find her......." mumbles Nagisa. "Nagisa....it's okay, I'm safe" I said as I gave him a hug. Awhile later I felt his arms wrapped around my body. "(y/n) I'm glad you're safe, I was so worried about you" whispered Nagisa. I didn't reply, I simply just continued to hug him.

After school

"Nagisa, here wear it" I said as I gave him my jacket. "W-What no....if I wear it you'll freeze" he said as he pushes my jacket back. "It's fine Nagisa, I have another one it's just a lot thinner" I said as I pull the other Jacket out from my bag. "Alright.........." he sighed as he put on my jacket.
