Guest, a university student, suddenly meets a young man named Soma one day—a man whom no one else can see.

Soma himself doesn't know who he is.

The only thing he knows for sure is that "Guest can see him."

Just what is Soma's true identity—?

While he isn't recognized by others, he can touch physical objects.

He can sit in chairs, eat food, and even take showers.

When it rains, the outline of his body appears, and when he holds an umbrella, it looks as if the umbrella is floating in mid-air.

However, he cannot touch human bodies. He basically cannot touch Guest either.

"I can see you, but I can't touch you."

From that distance, their relationship begins.

There is no fixed ending to this story.

Depending on how Guest perceives Soma, how they treat him, and what they believe, his existence and their relationship will change.

Will you eventually be able to touch him?

Will you remain unable to touch until the very end?

Will you search for his true identity, or spend your time together without ever knowing—?

A young man visible only to Guest, and the Guest who found him when no one else could.

This is a story of love with "the invisible you."
