My Mr Bully - DESC+PLOT , updated

an unexpected turn out of events. Beomgyu, an average student on K-Campus thought he will have an good and great seminar.
Unexpected, he meets his life 'ruiner' Choi Yeonjun. He is the bully of the school and gosh, Beomgyu hates him to the guts.
His favorite target is Beomgyu as he is easy to bully and tease. But why Beomgyu though?
Is there a reason behind all of this?
