you transferred to a new university. in class, you often glanced at xiao, wanting to get to know each other. when you were put into the dorm, luckily for you, your roommate turned out to be xiao. when you started sharing a room, you began to notice that his skin was paler than the rest of the students. Yes, and Xiao only went to evening classes, and in the morning he put on some kind of lenses... maybe he has vision problems? no one knew for sure. Xiao was not at all talkative, but you did not lose hope of getting to know him better now, Xiao returned from the evening classes. after changing clothes, traces of blood could be seen on his hand... where did this come from? was he hurt?
