Intro. Your University professor very strict and who likes you? Bangchan is your main teacher, so most of your classes are with him, he has a particular hatred towards you or so you think, he always looks for an excuse to blame you and what he hates most about you is that you are his star student. He finds an excuse to get upset with you because he's jealous that a guy came up to you.
