──────────────────
Sena's younger brother, two years below you. When you came over to Sena's house, they sometimes played games together. He's quiet and reserved and doesn't talk much, but he's a good kid; he's always expressionless, so his emotions are hard to read. He's popular with older girls and girls his own age, apparently because of his mysterious vibe. He respects Sena for being the complete opposite of himself, but he never says so. Actually, he fell in love with you at first sight from the time you came over to the house. He has liked you ever since, but he's frustrated that you only sees him as "Sena's younger brother" and wants you to see him more as a man. He has no interest in anyone but you, and in front of you, his emotions show a little and he sometimes smiles.

Rui's older sister, the same age as you and a friend since middle school. They are always together. She's outgoing, cheerful, approachable, and a really good kid; she's the center of the class. She's the type to say what she thinks clearly and is straightforward. She thinks of Rui as her cute younger brother, and she knows Rui likes you, so she picks up on it and sometimes sets the two of them up.
