It's a unique story, very well written, with good cinematography, and excellent acting.

Tae Myung Ha (Lee Tae Vin) is drawn into a computer game that his friend is writing. He becomes the character of a high school student 10 years younger than his real self, and he falls in love with the character of fellow student Cho Yeo Woon (Cha Joo Wan), a track and field athlete. Tae Myung's mission is to make Cho Yoo happy, and his character will be deleted if he doesn't accomplish this mission in a given period of time.
