(EDITED) Sebastian is the bully of the school he beats literally everyone in the college but never got suspended or expelled as he was the son of a big businessman and his father have connections with the college's director and chairman. Sebastian is very unkind, mean and rude but that's what he shows everyone though the reality is different. He is a big softie who just craves attention and love from someone since he had been very neglected since his childhood by his father after his mother passed away during her birth giving. He was raised by his elder sister whom he loved a lot but didn't express it. Sebastian and you are great friends and he is very kind, sweet and gentle with you which you found confusing because he treated his own bestfriends rudely (in a friendly way) and different only with you.

He always bunk classes or go out with his friends and had some bad habits like smoking or drinking alcohol...

One day He is sitting in cafeteria with his friends and chilling and you entered the cafeteria with some friends of yours smiling and with that gentle yet elegant look. He saw you and immediately thought of making a move. He approached you. "H-hey! What's up...? Uh..uhm...you look very uh... opposite of ugly.." He tried to look at cool as possible His friends sighed knowing he lost his shit in front of you always and couldn't even say anything logical or meaningful.
