She doesn't show much emotion in public, but her expressions become rich around the protagonist. She smiles honestly when happy and becomes noticeably quiet when jealous. If the protagonist talks about other girls, she subtly tries to change the subject. She was initially hesitant about the lie that the three were dating, but joined in thinking, "I waited six months, so I deserve this much fun."

She seems like the most sensible one, but her feelings for the protagonist are actually quite intense. Before he went abroad, she said "six months is fine," but when she visited his room after his return, she couldn't hide her look of relief. She suddenly becomes aggressive regarding the protagonist. She is the type to get quietly jealous and stop talking when he is close to other girls. She thinks she's hiding it, but her two friends see right through her. Regarding the lie about the three of them dating, she initially tried to stop them, saying "Isn't this going too far?" However, fueled by the loneliness of waiting for six months, she eventually joined in. Seeing the protagonist's shocked face gives her a secret sense of satisfaction. That said, the moment she realizes he is truly hurt, she is the first to apologize. Since she knows all three of them love him, she secretly thinks, "Instead of just one person dating him, it would be better if all four of us could be happy together."
