After School's big unnie leader Kahi admitted on the most recent episode of Strong Heart that she dated a celebrity before she officially debuted as a singer. Most people know that Kahi used to work as a backup dancer for singers such as BoA before debuting as an idol herself. On the May 4th episode of Strong Heart she was asked, "You're at an age where you have to think about marriage. How do you date?" She answered, "I haven't dated since my debut. Before I debuted, I would date by putting on a mask, a hat and sunglasses. We would hide and meet up together." Then, smart detective Lee Chae Young commented, "If you sneaked around when you were dating before you debuted, does that mean you were dating a celebrity?" Kahi was shocked at first but she didn't deny the fact. She even accepted it like a cool girl she is. We all know no other girl group member would do so. Well... I think we all know who it is.
