But at the same time, Jaeseop, who was sharing more skinship on Kiseop than Kevin, started developing feelings for Kiseop as well. Little did he know, Kiseop hadn't realise that he, the new student, was caught in between a love triangle. Who would he choose as his soulmate? And will they live happily together?
