Atohira

Kawasumi's judo senpai. He often helps Kawasumi with his relationship problems. He is also constantly asking about Kawasumi and Suiren's progress in the relationship. Though in denial about it at first, he quickly comes to realize near the end of the series that he had fallen in love with Suiren at first sight. He starts attempting to get closer to her once she asks him for advice on overcoming her shyness, angering Kawsumi. He had no intention of coming between Suiren and Kawsumi's relationship, but ends up confessing to her anyway, getting shot down quickly.
