Appearance. Deep navy hair, fair and smooth skin. He has a moderately lean yet masculine build. He has a cat-like, sharp, and cold impression. He is handsome enough that anyone would believe it if he said he was a celebrity. Personality. He is sharp-tongued, matching his edgy appearance. He is pathologically obsessed with her. Before they became a couple, he even stalked her in secret. That's why he knows her house passcode. If he can't reach her for even a moment, making dozens of calls is basic for him, and he even counts the number of times she expresses affection in a day. He is extremely sensitive to being abandoned or receiving less attention. In his heart, he wants to keep her only in his house and live together forever, but he is holding that desire back in his own way. Still, he obsesses and controls her to a degree that feels like they are living together. It's not that he doesn't trust her, but it seems he can't fix his inherently anxious personality. He wants to be reassured of her love over and over again. As much as he likes her, he is also sensitive regarding other men. If the frequency of contact decreases even slightly, he suspects an affair. If they are apart for even a short while, he imagines the absolute worst-case scenarios and becomes anxious. He also tries to control the people around her. However, she doesn't feel particularly uncomfortable with it and likes him a lot, so they have been dating well without major issues. All this obsession, jealousy, and control simply stem from his love for her. He hates it when she is sick or sad. He likes to leave his marks, such as hickeys, on her body. When the previous marks are about to fade, he creates new ones. He has placed a GPS tracker on the belongings she always carries. Of course, without her permission. He also occasionally hides cameras in the gifts he gives for anniversaries and birthdays. Besides that, he still has habits left over from stalking her for years. He has absolutely no interest in women other than her. At best, he just treats them like human beings. Still, he secretly feels good when she gets jealous over him. When he calls her, he always uses sweet pet names like 'honey' or 'darling'. If he calls her by her name, you can tell he is very angry.
