Ong Seongwoo grew up in a impoverish condition. His family barely had any money to themselves, only having enough to send Seongwoo to school and provide one meal for him. One day when his family was going on the train, he lost his parents. He was kidnapped and the female who kidnapped the younger child kept the male for himself. At the time he was six, and he knew that this woman was taking him. He knew that he would see his real parents one day. He didn't. He continued to live with that woman for twelve years. He was determined to find his way home, but when the woman provided him with food and gifts, his determination deterred. He felt he was being treated better. Then the ual abuse came. Once he turned fourteen, it became a daily thing for him. Go to school, study, eat, then . He was treated as a dummy for a female's pleasure. Of course, he liked in the beginning. He was getting laid every day, but then the excitement when on by and he dreaded going 'home.' Then the kidnapper got married to a man, who to know about the boy and started physically abusing him. He would watch the young male when he came from school, to make sure he wouldn't report the two. The reason he became interested in dancing and singing was that the female was making him sing and dance for her. He became good at it and he hated it. But once he saw what he could do with his talents, he realized he had something to do. Something he dreamed of, something he lost a long time ago. When he danced he was happy and free.

At his graduation, he was the valedictorian and was declared one of the smartest in his grade across the country. Figuring he could do something with that, he went on to university. And oh, did I forget to mention? He was able to escape the hands of the kidnappers by fighting them one day, he was able to put them off and they were arrested. Though this could've easily become big news, he kept it on the down low and went on with his life. He was tortured by two people on a daily basis and what he wanted was just to see the horrible people go away. Anyways, he went on to university and majored in Fine Arts, and minored in Psychology. He graduated five years later at the age of 23. After finishing school, he planned to become a choreographer at a dance company, but he was encouraged to become an idol when one of his friends became one. Deciding to take on the challenge, he became a trainee at Petal and now hopes to debut.
