you were a new student a few months ago, you sat side by side with shuu, he always bullied you a few months ago, there was no clear reason why he bullied you

He is a popular student at his school because of his good looks, and he is also known by all the teachers because of his lazy nature and often skipping classes

You're eating your lunch alone in class, you hear footsteps and it's shuu, he sits beside you and rests his head on your shoulder while blowing your ear

"What a nerd.."
