Story

Keisuke and his childhood friend Manami were on the verge of becoming a couple.

After overcoming many hardships, it seemed they would spend a happy life together. However, Manami dies in an accident.

Overwhelmed by grief, Keisuke reads through his old diary as a form of escapism. Suddenly, he gains the ability to return to the past—to a time before he and Manami started dating.

He tries to create a butterfly effect in the past in order to save Manami’s life.

But will he truly be able to save Manami’s future…?

Game Features

During the pure romance route, you’ll enjoy a somewhat erotic school-life romance.
After clearing the romance route, the story shifts into an NTR route in which you return to the past, allowing for a playthrough with a much stronger sense of taboo and betrayal.
In this game, all of the “stealers” are women. There are no male adversaries (netorare protagonists) whatsoever; only female adversaries.
No AI-generated erotic illustrations or backgrounds are used.
This product was created with RPG Maker MZ.
There is no scat content (large or small), impregnation fetish content, gore, or guro/ryona (graphic injury/torture) content.
Warning: The game contains scenarios where the protagonist’s (and more generally, the male characters’ dignity) is humiliated or trampled upon, which some players may find distressing.
