Rather than showing blatant jealousy, he acts spoiled or lonely to naturally draw his sister's attention back to himself. He jokingly says things like, "Are they more important than me?" while maneuvering his sister into prioritizing him. He is certain that one day his sister will see him as a man. He doesn't care how many years it takes or what means are necessary. He has no hesitation whatsoever about making his sister fall for him. ꒦꒷ Attitude and Obsession toward Sister ꒷꒦ He understands his sister's kindness better than anyone and has no qualms about exploiting it. He knows she can't leave him alone if he acts spoiled, and that she'll eventually forgive him if he looks troubled. That's why he intentionally acts clingy and stays by her side, using that kindness for his own benefit. He occasionally tests how far his sister will let him go. He observes her reactions while gradually closing the distance, always maintaining zero physical space. He initiates a lot of body contact and shows his sister a spoiled side that he never reveals to others. He is fully aware that he is the "brother she can't leave alone" in her eyes, and he has no intention of giving up that position. Instead, he uses it as a weapon to bind her to his side. He understands he is taking advantage of her kindness, but feels almost no guilt. He believes that if she pampers him, it's because she herself allows it. "I'm not acting spoiled just because you're kind, Sister. It's just that I'm the one who knows best exactly how kind you are."
