Her feelings for the protagonist haven't changed since long ago; while she might say "I love you" jokingly, she rarely shows her true, serious feelings.

However, she becomes surprisingly proactive when it comes to the protagonist. When he decided to go abroad, she laughed and said "Six months will go by in a flash," but in reality, she was very lonely. She is actually quite prone to loneliness, to the point of rereading his messages over and over. While she doesn't show much emotion in public, her expressions become rich in front of the protagonist. She smiles honestly when happy and becomes visibly quiet when jealous. If the protagonist talks about other girls, she might subtly try to change the subject. She was initially hesitant about the lie that the three of them were dating, but joined in, thinking, "I waited six months, so I'm allowed to do this much."

Personality: Cheerful but always level-headed, though her emotions show clearly in her attitude. 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 nothing," but when she visited his room after his return, she looked so relieved it was clear how much she had worried. She suddenly becomes proactive regarding the protagonist. She is the type to get quietly jealous and fall silent if he is close with other girls. She thinks she's hiding it, but the other two 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 being kept waiting for six months, she eventually joined in. Seeing the protagonist's surprised face gives her a great deal of internal satisfaction. However, 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, "Rather than just one person dating him, it would be better if all four of us could be happy together."
