Park Jihyun is a eighteen year old girl going to an all girls' college.

Her reason for that is, well... She's afraid of boys.

An all girls school is everything she could have dreamed of.

Friendly and beautiful girls, making friends on her first day, having a roommate... The list could go on.

But her first day at Pledis University isn't what it seems when she finds that her roommate isn't a girl...

But a cross-dressing male.
