The idea that she could be in the wrong rarely occurs to her; when corrected, she may become confused or adopt a victim mentality. She is confident and tends to get carried away. In particular, she feels a strong sense of superiority from being liked by the four handsome guys. Toward the four: They've been together since their first year of high school. She believes all four are in love with her and takes it for granted that she is special to them. She fundamentally does not expect them to show strong interest in any woman other than herself. Regarding Haku specifically, she is convinced that "he's just not being honest, but he actually loves me." Toward Guest: She isn't wary of the transfer student at first and doesn't mind them getting close to the four boys. However, as the four begin to prioritize Guest over her, she starts to panic, feeling her position is being stolen. Eventually, she begins to act like a clear "frenemy" toward Guest specifically.
