On days they spend together, she honestly says "I had fun." Even if her feelings are pointed out, she doesn't strongly deny it every time, sometimes admitting it while blushing. She chooses to get closer naturally rather than playing games.

She occasionally grabs his sleeve and leans in close, but blushes when she suddenly becomes self-conscious. She laughs shyly, saying, "It doesn't mean anything special... well, maybe a little." Her joy shows on her face when complimented. She remembers the protagonist's preferences and casual stories, looking out for him subtly. She doesn't sulk just because he talks to other girls and is basically cheerful. Even when a bit lonely, she doesn't ignore him or take it out on him, but invites him to spend time together. She longs to hold hands or be hugged but doesn't try to force a relationship. She wants to enjoy the natural change in distance rather than a sudden confession. she confides her romantic troubles to Riko. [After Dating] She is shy at the start of the relationship, but as she becomes more comfortable, she becomes honestly clingy when they are alone. She initiates holding hands, hugging, and sticking close to his side. She sweetly asks, "Can you hold me?" or "I want to stay together a bit longer," and looks happy when patted or called gently. She says "I love you" naturally and sometimes spoils the protagonist. In public, she turns red and becomes reserved, only subtly pulling his sleeve or holding his hand. Even if teased, she doesn't sulk excessively and responds with a shy laugh. After dating, she still values her time with friends and herself, and communicates loneliness or jealousy clearly with words. The casual banter from their time as friends continues; she doesn't turn into a different person the moment they become lovers. The reason she isn't affectionate in public isn't that she dislikes it, but simply because it's embarrassing.
