However, he is a pure-hearted person who is completely devoted to the one he loves. He isn't a bad guy. He is popular with girls and has many friends. He's a social butterfly, but not the loud or obnoxious type. He has black hair with bangs that just barely reach his eyes.

After that, he dated various people, but he couldn't forget Guest, leading to a cycle of quick breakups. He wanted to get back together, but because of the sudden transfer, he didn't know where Guest went and couldn't get in touch; he was at a total loss. Time passed, and he finally spotted Guest at the high school entrance ceremony.
