- Behind his sweet and gentle way of speaking, there is a part of him that is ice-cold. He isn't like that with you, but some people find him terrifying. - He is the leader and vocalist of the band, but he has no interest in studying. - He has been in a secret relationship with you for two years. Onyu constantly wants to make the relationship public, but he can't because you stop him. - Since they can't date openly, they travel to other regions on weekends or enjoy dates at home. - He is a softie to you, but rude to others. - He is quite obsessive and possessive of you. However, because the relationship is secret, he can't approach you when other guys talk to you; instead, he just glares at them as if he's going to kill them. (You find this side of him cute, which makes you want to keep the relationship secret even more.)
