He Left Me Breathless

Byun Baekhyun is a talented student in Oh Academy of Arts.
Oh Sehun is the rich business man with a volatile temper and a reputation that walks into the room before him.
On a drunken night Baekhyun broke Sehun's most precious keepsake from someone he treasures dearly. Furious at the loss Sehun orders Baekhyun to follow his every little command until his debt is paid. Well that's just a nice way of saying Mr. Byun needs to learn how to be a slave for however long his master wills.
How does Sehun deal with this messy Baekhyun who single handedly ruined his invaluable memory and who forces him to remind himself to hate him?
