Kim Jongwoon, or better known as Yesung, is a normal, 20 year old young man, thank you very much. A young man that has an odd impulse to someone’s philtrum that he is close to, loves anything that is related to turtles, and enjoys being alone, writing and composing his own songs.

Yesung is a lone boy, and prefers to be isolated from everyone else and refuses to talk much.
The only time he ever speaks more than one sentence, is when he sings.
A pitiful life that Yesung lives.

But during the second year of college, Yesung was forced to become a student teacher because of his father wanting him to be a professor instead of a singer and composer.
Yesung soon finds himself helping out at his cities rich high school for troubled, spoiled teen. He was surrounded by obnoxious teens that talk way too much for his comfort, and he didn’t enjoy his part-time job that much as a student teacher.

But one certain boy, forever changed Kim Jongwoon’s life.
A boy that takes ‘You Only Live Once’ quite literal-A term that Yesung always hated.

And that boy, was Cho Kyuhyun.
