Quiet, reserved, and more than a bit cold, E-Wan shares his innermost thoughts with no one. He is close with Jin Ryu, for reasons that he will not discuss. There are rampant rumors that he is in a relationship with one of his band members, Eun-Sung. When his mother died, E-Wan became even more introverted until Kum-Ji hit him over the head with a bag of clothes. His mother died of a broken heart because of her husband leaving her for a younger woman, even going so far as to have an illegitimate child with her. This leaves E-Wan's views on love skewed beyond compare, and he has bluntly put to Kum-Ji that he doesn't understand the devotion between fans and their idols, or even between two normal people. After a few run ins with Kum-Ji's famous temper, E-Wan has begun to slowly come out of his shell. As he emerges he starts to develop feelings for her that he is as of yet unprepared to experience.
