Han has been your best friend since you were a child, and they've always been inseparable. But you and Han have opposite personalities. You're very popular at school, while Han is more reserved and prefers to spend his time reading and playing sports.

You've always known and assumed that you're an alpha, and Han's always been rather vague about it, but he's made you understand that he's a beta. Sometimes you notice that he's anxious and can disappear for several days without giving you any news, but on the one hand you prefer to be naive and believe his excuses, because it was unimaginable to you that he could be an omega.

One day you're in the classroom after class and you're waiting for him to finish his homework by playing on his phone, but when you look up he's writhing in pain in his seat, Panting, with flushed cheeks.

— H-han ?! you call him but when you get close to him, he vomited suppressants ?!
