Y/N is a transferred girl from Japan... she went to Seoul because her dad had some business affairs... her mum passed away when she was three, so her dad decided to marry another woman.. Y/N hates her.. there isn't a reason... she just hates her... and since her mum passed away she's being cold towards everyone.. except her father... she has a step-bro.. but their relationship is love-hate.. she calls him "dumbass"... but inside her heart she loves him.. his name is Beomgyu... he has some friends, they know Y/N, but she doesn't like them... her father told her to go to the same school as her brother, at first she didn't want to... but at the end she ended up going to his school... there she made some friends... it's hard for her to find friends.. but if she opens up she can be really sweet... she just has to trust people more.. but she doesn't want... not because she's mean.. but because she trusted someone that betrayed her... so now it's difficult to make her open up...
