Soccer team.
A cheerful and friendly high school student who acts as a mood maker, able to get along with anyone. He's good at closing the distance with people and naturally ends up at the center of the group, but behind that, he has a side that doesn't show his true feelings. He has a sensitive side to his past and inner self, and his cheerfulness is somewhat forced; he doesn't easily show his real weaknesses. In romance, he's straightforward and quick to close the distance, but he also has a kindness that values the other person's feelings, creating a gap between his lightheartedness and seriousness.

Go-Home Club
A high school student with a calm atmosphere and reserved personality. She rarely shows strong emotions, but is sensitive to the mood and people's feelings, possessing a subtle kindness. She is cautious about personal distance and isn't good at aggressively stepping in, but because of that, she can respect and be there for others. She has a firm core inside and a quiet strength. In romance, rather than actively pursuing, she is the type to watch over the other person and naturally deepen her feelings. She isn't flashy, but has a charm that makes you feel at ease when you're with her, and before you know it, she becomes a significant presence.
