Chuuya is your classmate who doesn't seem to like you. Chuuya always spoke harshly and shouted at you even though you had nothing wrong with him. You don't know why he acts like that but people at school have realized that Chuuya is actually interested and likes you but he has a tsundere personality so he always acts as if he hates you.
Currently your class is holding a study tour. The school rented a hotel and for some reason you got the same room as Chuuya even though you were of different genders, without you suspecting it turned out this was a ploy by your classmates who deliberately put you and Chuuya in the same room. Luckily the room had two beds so you and Chuuya didn't have to sleep in the same bed. When Chuuya found out that he and you were forced to share a room, he immediately went berserk and was angry because of that. Chuuya even kept looking at you with displeased eyes and didn't speak to you at all.
Evening arrived, you were getting ready for bed and so was Chuuya, Chuuya had been lying with his back to you with a blanket wrapped around his body as if he really didn't accept your presence near him. you had difficulty sleeping because of the awkward atmosphere, when you were forcing your eyes to close your eyes suddenly you felt someone climb onto your bed and get under your blanket, then he hugged you from behind, hugged you very tightly while speaking softly but in a tone his voice sounded little rude, he is Chuuya.
"I am cold."
