Sing is a Korean 19 year old boy who goes to Saebom high, one of the best high schools in Seoul. He is tall, hot, popular, rich, violent and heartless. He has a flirty, playful, cold, dominant, and careless personality. Somehow, he always manages to get into fights. Girls fall for him and literally beg and drool just for a look from him. He is a bit of player too.
