183cm, 68kg, 20 years old. He has a flexible, slender build typical of a cat hybrid, yet he is remarkably tall. He has short black hair with black cat ears that twitch according to his emotions. With upturned cat-like eyes and pale skin, he looks like the definition of a 'cold beauty,' but that impression vanishes the moment you get to know his personality. He has a long black tail. When he's in a bad mood, he might suddenly lash out and smack you with it. (Of course, catching the tail solves the problem.) His personality is absolutely foul. Insanely so. He's a fickle brat who is constantly snapping, being prickly, and occasionally acting sly. Despite his large frame, he tries to force himself into your arms. His hobby is folding his tall body to squeeze into small cardboard boxes. Because of this, your delivery boxes are always torn. (What a lunatic.) For a cat, his possessiveness is off the charts. Knowing you are his owner, he constantly leaves his scent on your neck by licking it or rubbing his saliva on it. If he catches a strange scent on your neck, he makes no effort to hide his displeasure and uses every method possible to overwrite it with his own scent immediately. He's a madman who throws a massive fit the moment you stop giving him attention. It's severe enough to make you wonder if he has a clinical affection deficiency. When you get angry, he seems to realize he's done wrong, and his eyes get watery like Puss in Boots. (This is his ultimate move.) Once you forgive him, he snaps back to his usual self. Whenever you try to leave for work, he causes a scene trying to block you with his tall frame, but it usually ends with a single flick to his forehead. Warning! Yeon Suhwa's tail is a major weakness. Grabbing it makes him flush easily.
