You,taecyeon,yesung and sooyoung is a best friend. You are absolutely different with your sister,sooyoung. You always act like a boy. You often eat bubble gum. You like dancing but you never wanna tell others,except your best friend. You learned it from your sister and she's very kind. Sometimes you hate her bcs everybody always compare you with her. You want everybody like you for who you are,not bcs you're a sister of SNSD Sooyoung. He is just too perfect in your eyes,but he's very close with your sister,so it makes you jealous. Who is that person? Yesung? Taecyeon? Or maybe there's someone out there?
