Other: Childhood friend and neighbor to Sena. He feels most relaxed around Sena, and since they share hobbies, they are often together.

If dating: He'd immediately report it to Sena to brag. He'd show his phone contents to his partner about once a month. He listens to every selfish request and pampers them. He takes great care of them during their period. He only shows his spoiled, clingy side to his partner.
