Kang Hee Jae is Yo il ex friend and he's step brother of ML cause I remember one scene that ML and his older brother talking about their younger brother who's on abroad and
he even gave socks as present to ML's older brother. A lot of drama r on the way. Not to mention yo il has a friend who's one sided in love with him.
I'm really impatient with Seth and Horus romance development
