Synopsis

Suhan, a high school student, feels frustrated because he can't get along with his younger sister Sunmi. One day, while visiting his friend Jinyong's house, he sees Jinyong getting along extremely well with his own sister. Jealous, Suhan hears Jinyong say, "I didn't always get along with my sister either, but this helped us," and Jinyong hands him a small stone.

That stone possessed a mysterious power to change things that happened in the past. Suhan uses the stone to alter the unpleasant memories he had with Sunmi one by one, and because of the changed past, he gradually grows closer to her. Suhan becomes absorbed in changing the past, and then unexpected things begin to happen...

Generally this genre of game is called Visual Novel. (Ex : NEKOPARA, Sakura series...)

As you read the story, your choices at branching points will change the development, and you'll be able to see various endings.

※ The Prologue version ends before the branches begin.

Purpose

The goal is to become close siblings with Sunmi by using the time travel stone.

When you travel in time, your actions toward Sunmi will change your present relationship with her.

Not everything that happens when you travel through time is necessarily good.

The ending will vary greatly depending on when you stop using time travel.

The Prologue version ends before the branches begin.
