Name of character: Park Jungsoo/Leeteuk
Age of character: 20
Place/job for character: Citizen

Leeteuk is Eunhyuk's very best friend. He has known the younger since Eunhyuk's been in kindergarten and has always been with him. He's very protective over his best friend and would try anything to keep Eunhyuk from hurting himself, even if he doesn't always succeed. He used to live with his parents until he decided to move out at the age of 20. He lived alone in his apartment until he took Eunhyuk to himself because he couldn't bear seeing all the pain and shame the younger went through without being able to do anything - the young boy refused to go to a psychiatry or to the police and he had promised not to force Eunhyuk to do one of those. He would end up in an orphanage and that would be worse than what they had just then.

When Eunhyuk started to go to a therapist though, he had to promise the younger to come along.

Even if it might seem to others that Eunhyuk is the only one who depends and needs that friendship, Leeteuk himself needs it as well in a way. The younger boy knows everything about him and even though he doesn't like to share his worries, he enjoys being near his best friend when something's bugging him. He can't imagine anymore what it's like to be without his best friend.

He was a very good student and now is good at his job. He has fun participating in his job and enjoys working with his colleagues. It almost never happens that he gets angry at someone and if it does happen, then he usually doesn't show it.
