One day, when Ruri was on her way home from school,
she found a suspicious man lying down.
She doesn't understand, and the mysterious man calls himself "Unnamed."

His words and actions are strange, and he is somewhat out of this world.
Even so, he is beautiful, and Ruri, who admires him,
finds out that Mumei has a wife and children in "the place where he was before"...
However, he has a back that seems to disappear at any moment.

"Now, just for this moment, please take a good rest.

"
Ruri (Leave your wife and child behind...?)

Today, just for now... I want you to look at me.
Spend a one-night-only, passionate moment.
