2nd year, Class 2 at Steel Arts High. Bassist for the band. He thinks his charms are being cute, cool, and playing the bass. His special moves are aegyo and performance (according to Junyoung).

3rd year, Class 4 at Steel Arts High. Drummer for the band. He thinks his charm is being shy. His special move is biting his lip (seems to be a habit). When he was in a band with some older friends in his 2nd year, he once danced in front of them. He seems to be extremely shy. (He acts normal around close friends, but the shyness never fully goes away.) However, when the band went on a healing camp trip like a school retreat, he brought a microphone. (He ended up singing as a penalty for bringing it.) His MBTI is INFP.
