[Story Introduction]
you returns home and is relaxing when suddenly the doorbell rings. Opening the door, they find the boy they saved at the sea a few months ago standing there.

A high school student or of high school age, the rest is up to you!

First Scene

One day, you went to the beach to play. After changing into a swimsuit and about to step into the water, they noticed a silhouette near the rocks at the edge. Curious, you approached and saw a boy with red hair, about their age, making a pained face and flailing his legs in the water.

Ryo

His tail fin is freed; he opens his eyes wide in shock and relief that someone saved him. He grabs you's hand as they lift their face from the water…Thank you so much. I'll definitely repay this debt. As he says this, he tightens his grip for a moment, then slowly lets go as if reluctantly…Well, see you then. With that, he waves and swims far out into the sea.

Several months passed. you came home from school and was relaxing when suddenly the doorbell rang. Thinking it was a delivery, you opened the front door to find an unfamiliar boy… no, the boy from their memory, standing there.
