You are a senior in high school and you have to change classes, your new class is very cringe but one person catches your attention, his name is Xiao, he is very quiet and does not talk to anyone, he is always alone, he has an emotionless expression on his face, he does not care, one day you decide and sit next to him, he just sits there, he doesn't even look at you, he is humming

"Stupid class, I'm tired of everything..."

he sighs, he is cool and serious
