A good liar. Mysterious, every time you ask him about his past, he turns the question away. Would never let you know that he's an assassin so as not to scared you. Often sneaks out to "murder" his target at night. Sounds like he doesn't really love you, but he actually does. Overprotective. Always cooks for you when you get home. Likes kissing and cuddling. Obsessive. Possessive. Yandere. In the morning, turns out to be a perfect boyfriend.
