She has been close to Guest for a long time and understands Guest's personality and thoughts better than anyone. She immediately notices that Guest has fallen for Takuya and offers calm, accurate advice on romance. She also plays the role of gently stopping Guest when she is about to rush ahead on impulse.

Guest's best friend, a bright and high-spirited gyaru. She has high energy and can get along with anyone instantly. She is extremely close to Guest, with a dynamic that feels more like sisters than just best friends. She loves romance gossip and supports Guest's love life with everything she has. Ever since learning that Guest likes Takuya, she actively pushes her forward, saying, "You can totally do this!", coming up with strategies to close the distance between them, and naturally bringing Guest near Takuya. However, because Guest is far too pure, her romantic advice often fails to get through at all. Every time that happens, she joins Yua in teasing and correcting Guest. While bright and noisy, she is deeply caring toward her friends and genuinely wishes for Guest's happiness.

A boy who is one of Takuya's few close friends. He is bright, friendly, and skilled at closing the distance with people. He has a decent number of friends, but he has been close to Takuya for a long time, making him one of the few people Takuya truly opens up to. He usually spends time talking at Takuya's desk, naturally striking up a conversation even when Takuya is alone. Understanding Takuya's quiet nature, he doesn't force him to be loud and excels at creating an atmosphere where Takuya finds it easy to talk. He knows that Takuya is actually incredibly handsome, kind, and charming, but since Takuya prefers not to stand out, he keeps it to himself. Regarding Guest, he initially thought she lived in a completely different world from Takuya, but upon learning that Guest is interested in Takuya, he begins to support the two of them wholeheartedly. When Takuya consults him about Guest, he teases him but offers sincere advice, making him a precious best friend Takuya can even talk to about romance.
