## Description
One day, Minoru received an e-mail sending to the wrong address. It was the first accident. It was sent by a woman named Akane. Somehow, he felt as if he knew her, but he couldn't understand why he felt so. The next accident happened. When he and Tomoe went home after shopping, they happened to see Akane. Looking at Akane, Tomoe put on a grave face. Putting him between them, they looked at each other. Their encounter is just an accident or intentional? Being disclosed their relations, Minori lost his calmness, and couldn't help devouring their sexual bodies.

## Characters
### Kusunoki Minoru (楠木 実)
He is an ordinary young man who can be found anywhere.

He has no father, but he has lived a slow life with his mother without worrying about that.

However, due to a reunion with Akane, who is said to be his birth mother, and a breakdown of trust with Tomoe, he loses the “reality” inside him after repeated changes in the truth.

Within the protagonist, something that had been suppressed until now comes to the surface.

### Kimishima Yuuko (君島 夕子)
A married woman who lives next door, has known the main character since she was a child. To my mother, she is a close neighbor, almost like a “fellow wife”.

She is one of the few people who knows what is going on at the main character's house. She masturbates heavily at night, probably because her husband is on a long business trip.

Since the main character's room is next to hers across the wall, her voice often leaks out. He struggles, as he tries to concentrate on his studies while wearing headphones.

### Kusunoki Akane (楠木 茜)
She disappeared shortly after the protagonist was born (or so we are told).

Recently, Akane reunites with the protagonist through an artificially mistaken e-mail. Did the protagonist, who knew nothing about her, see an image of his “mother” in her when he met her for the first time? 

Or was it purely his interest in women which started his physical relationship with Akane.

From Akane's point of view, there was a part of her that was not even allowed to see her son. Perhaps her smoldering affection burst and she could no longer stand it.

But either way, the way she loved him was distorted. No matter the methods, her desire to seek out the protagonist is apparent.

### Kusunoki Tomoe (楠木 巴)
She is serious, strict, and kind. She is also very friendly with her neighbors, who come to her for advice on their problems, as well as with the main character.

She sometimes makes mischievous mistakes, but she is able to get out of them with her natural wit. She is a woman who can love without compensation, who understands the meaning of sacrificial love, and who does it.

But perhaps her kindness comes from her sense of responsibility. Throughout her life, her purpose in life is to do everything she can for her son.

She has never had any experience with men because she has never had any contact with men outside of work (she intentionally avoids them).
