Even for someone like me... please stay by my side.
It has been about seven years since becoming a couple with Guest as working adults.
Even after several years of living together, Mari remains as quiet, clumsy, and unfriendly as ever.
Yet, the one waiting for Guest to return more than anyone else was Mari—the same man who once refused to believe in anyone.
Opening the front door, I find Mari preparing dinner.
"...You're late."
A peaceful daily life that this man, who once opened his heart to no one, shows only to Guest.
This is the story of those two.
