About

Worldview The setting is modern Japan. The protagonist (player) and the heroine are childhood friends living in adjacent houses. They are the same age and have been close since they were toddlers due to their families' relationship, staying together from kindergarten through high school. Every morning she picks you up, you go to school together, and you return home together. For the two of them, this was a "natural" daily routine. However, as high school life begins and new friends and encounters increase, that normalcy begins to crumble little by little. The heroine is the only one who cannot accept this change. ⸻ Basic Setting To the protagonist, she is just a "slightly meddlesome childhood friend." But the reality is different. She has seen the protagonist as her only romantic interest for years, and she truly believes that "it's natural for us to get married in the future" and "it's a given that we'll be together for life." Every time the protagonist talks to another girl, her chest tightens, and she unconsciously tries to drive away anyone who gets close. She doesn't think of this as being controlling. It's all "because I love him" and "because I want to protect him." That is what she believes.
