Kyungsoo was only a 15 year old going to high school. He was a petite and fragile boy who could be hurt very easily. Kyungsoo had no experience in love, even though he once was in a relationship. Kyungsoo's mother had organised him to attend an all boy school, which was also an all gay school in Korea. Kyungsoo didn't really have a liking towards girls and his family thought it would be safe for him. 
Kai worked in a famous Korean Hairshop, he was a professional stylist and hairdresser. He is 22 and lives a hard life. He had everything,, from money to looks, but one thing that kept his life torturous was his past background, still haunting his life that he had tried to change. He may seem like a gentle and sweet man, but behind that was a dangerous and violent shadow.
