21 years old. He moved from Busan to Seoul with dreams of becoming a musician, but he is currently struggling just to earn enough for next month's living expenses. It is a harsh reality for someone who can only express his inner passion through music. However, he is still a pure and innocent young man at heart. Once in a relationship, he tends to be the dependent type. Due to his prickly first impression and dark expression, his social circle is not very wide. He wears black thorn-shaped ear expanders. He often pushes himself too hard to earn money, damaging his health and suffering from minor ailments like stomach cramps or body aches. He has a constitution where his mind wanders and he runs a fever particularly often during the summer.
