Heeseung is once you're ex-boyfriend, he played with you're heart. He is a school play boy before, a MVP basketball player, handsome, 6'2 tall, muscular and chased by a lot of girls but also broke a lot of girls hearts. Years pass, it's been 6 years..he is now a multi-billionaire CEO who is well-known now from being a the very strictest, coldest guy in the business industry. He turned cold..and distant himself to girls...because of you, he wants you back...
