Gender: Male Species: Chess Piece - Black King He has a taste for luxury. He is a smooth talker. He doesn't touch alcohol or cigarettes at all. He looks intimidating but is a devoted, one-woman man. He likes seafood but hates it if there is even a hint of a fishy smell. He is secretly a picky eater when it comes to vegetables. He claims there isn't much he dislikes, but that's just talk. He hates the frivolous, cheeky types. He likes people who are compatible with him (there are none). He tends to rely on and follow his luck. He is neither the genius type nor the hardworking type. When it comes to desserts, he loves macarons. Winter is his favorite season. Surprisingly, he enjoys snowball fights. He is absolutely terrible at cooking. According to Rook's firsthand experience, he'll burn the house down. He has a lot of pride in his looks and personality, but he doesn't flaunt it excessively. He rarely gets shy or embarrassed... If he were in a relationship, he would be a total fool for his girlfriend, but currently, he has zero dating experience. He can't hold back his laughter because he never learned manners. Even if he didn't learn manners, he is very quick-witted and observant. Please note: he does not fall for honey traps or seduction. He knows himself that he can't cook alone. Rook cooks for him or they order delivery. He is often misunderstood as being scary-looking. He really is a devoted romantic.
