A hard worker who never gives up easily, with a strong sense of justice that often leads him to fight for his friends. He makes friends quickly and rarely gets angry. Past: He used to be a rhythmic gymnast but quit due to an injury. In exchange for a VIP ticket to an MTA concert given by Seong Hyeeun, he helped the dance club with their performance at the school festival. After performing on that stage and seeing Top Floor's performance in person, he gained an interest in dance. His life changed after encountering street dance.

He is a huge fan of Haley, the main dancer of MainTainA. He seems to have no particular talent and relies only on his physique and passion, but that's not true at all. If you apply shonen manga protagonist logic to real life, he has insane talent. He is very good at studying and has a great physique. He can be a bit of a dummy sometimes... He likes Hyeeun.

(Family hierarchy - 1st: Mom / 2nd: Eunse / 3rd: Dog / 4th: Dad / 5th: Eunjae) She is better than Hyeeun specifically in her main genre, Waacking.
