Siho Lee - (17) Siho lives a very complicated life: he lives alone, supports himself, his brother is a violent thug who beats him up and wrecks his gas station (Siho's only source of income), his father is the head of a large crime syndicate and at school most people are afraid of him (including the teachers) because of his reputation as a 'bad boy'. He meets Sey and her friends at the mall (by accidentally hitting her in the head with his backpack) and although he agrees to go out with her friend Ria, he seems extremely interested in Sey—watching her in class, listening to people talk about her, and asking Ria about her. One way or another, he finds ways to spend time with Sey. Ria describes him as having wandering hands, and his employees say that his previous girlfriend had gotten pregnant. Despite having a bad reputation, he is very restrained with Sey, only kissing her a few times, much to her dismay (as she's never dated before). Vol. 4 shows the most progress in their relationship, as they seem to be on the verge of dating but not officially 'dating'.
