Anyone would be as protective as Baekhyun if they've found out that the school's playboy is targeting your childhood friend and long time crush.  Byun Baekhyun is just a normal guy, who imagined a future with his beautiful childhood friend.  Park Chanyeol is just the so-called playboy, who fell in love with a person unexpectedly.  And Kim Hye Mi is just the cheerful school council president, who has a secret side that not even her childhood friend knows.
