You, Jun Sungsook, are a shy and cute average girl with a big heart when it comes to being in a group of small friends. Jung Hana, your school's player, wants to win your heart dating by different girls just to make you jealous, but you always reject her a lot because you were worried that she'll "play" with your heart.

Despite the fact that you never like Hana, you just want to be with your older sister, Jun Hyosung, and your best friends, Song Jieun and Han Sunhwa. They know you don't like her and wanted you to just go for it, but you refuse since you are too stubborn to do it.

Will Jung Hana win your heart or get rejected and give up?
