You were born in a really rich family. Your father wanted to make you the executive director of his company. But no one knows you were the daughter of Choi Company and Enterprise. You had 3 elder siblings. Choi Siwon, your eldest brother and the one who dotes on you but is a bit stubborn. Choi Sooyoung, your darling elder sister who helps you when needed. Choi Seungcheol, your brother you dotes and cares for you the most. At your new school, you met 7 boys who are charming, handsome, smart as hell, but freaking playboys. Will you past through them?
