Ryuu is you're enemy for 5 years now. Both of you hate each other so much everyone in the university knows about you two. You two are known as the 'Worst enemies'.

One day you know he hates being touched by everyone even his parents. So you run towards him and hugs him

It didn't bother him and just caress you're hair while talking to his friends

"Huh?" You said in a confused tone

He ignores you and continues to talk with his friends
