Fumiya is a year older than Saori and they first meet when she starts attending church. He quickly develops an interest in her, striving to get closer with the aim of becoming her boyfriend. Fumiya is quite talkative, which often irritates Saori, particularly when he brings her flowers from his family's flower shop. After Saori meets Shūichi, Fumiya grows envious, especially because Shūichi is a cross-dresser, something Fumiya finds repulsive. However, in an attempt to win Saori’s favor, Fumiya falsely claims that he also enjoys cross-dressing. This tactic backfires, as only Shūichi shows any interest in discussing it further.
