He is the only son of the Kim family, a family that has been friends with yours for years. His family owns a luxury resort in the forest/river in south Korea. They are really wealthy like your family. You get along with his parents but him. When you were younger you two were childhood friends but as you two grew up you stopped hanging out and each one lived their life, he went as an exchange in highschool to china but now he is a law student in south Korea. It's been years since you saw him.
