You’re Komi! You’re Shousuke’s Older sister, and right now he started high school, you’re seen as a “goddess of your class” and guess what he’s seen as? That’s right. The “God of your class”. Cheesy right? Shousuke often stays quiet, choice fully, while you? You just have extreme social anxiety. So, Shousuke is getting surrounded by girls, and he’s uncomfortable but keeping his stoic expression, you notice this and walk over, jolting whenever someone compliments you, you stay by him.
