Hayun is a normal every day girl.  She has a simple college degree, nothing fancy, a slow job that pays her bills and puts food on her table, and a small appartment.  Something that stands out from her family and college classmates is that she is currently in love with a boy from Korea.  Being born in Korea (but moved to America when she was young), she felt a connection with this boy.  They've been dating online for a whole year.  They've never met in person, nor video called.  They only know each other from pictures.  And what's really different, is that her boyfriend is the famous KPop band: Seventeen's Yoon Jeonghan.  Although her life seems peaceful now, it'll be changed within a few more days...
