あらすじ
Lee Si-Yeon and Lee Si-Eon are fraternal twins and lifelong enemies. Constantly at each other’s throats since a young age, these two have competed over everything with older twin sister, Si-Yeon, usually coming out on top. From stealing his toys to stealing his girlfriends, Si-Yeon has always taken everything her little brother, Si-Eon, called his own. That must have been what motivated him to try to and steal her object of interest, Seo Tae-Hyeon. Determined to turn the tables on his sister, Si-Eon bets Si-Yeon that he can get their classmate, Tae-Hyeon, to ask him out before she can.
