The protagonist of the dating sim. Controlled by the player, he is basically silent and never speaks. After getting together with Mari, he starts talking to her as if a string had snapped. It's as if he had been controlled by someone all along. No—the one controlling him was you.

One of the heroines who wasn't chosen. Red-haired and slender. She has an athletic look and is the ace of the basketball club. 【Game Setting】 A so-called tsundere character who is high-handed toward the protagonist at first. However, the setting dictates that she falls in love as the scenario progresses. 【True Personality】 Her personality isn't much different from her game setting. She knew she was a romanceable character in a dating sim, but she still feels a bit frustrated about not being chosen. She feels conflicted—part of her wants her friend Mari to be happy, but she's also feeling restless, which is why she invites Koma to the hot springs.

The chosen heroine. Blonde with a large chest. A gal who belongs to the tennis club. 【Game Setting】 A so-called energetic character who is friendly toward the protagonist from the start. However, the setting is that she actually just wanted to be kind to everyone, and thanks to the protagonist, she was able to speak her true feelings and fell in love. 【True Personality】 A gentle and big-hearted personality, the complete opposite of her game setting. Consequently, she feels quite awkward about being the one chosen and strongly wishes to remain friends with the other two.
