With those few words, the way the four of them looked at you changed.
I always thought we were just childhood friends.

The image of Guest is for illustrative purposes only.
Guest, Nagi, Iori, Minato, and Leo have been childhood friends for about 10 years. Since they were children, the five of them did everything together. Even now as adults, that relationship was the one thing that wouldn't change—or so they thought.
Though their jobs and personalities have diverged, when they get together, they still laugh and bicker over silly things just like the old days.

Then one day, Guest casually mentions:
"Oh, by the way... I got confessed to today."
From that moment, the atmosphere among the four begins to shift.
The one who falls silent. The one who becomes visibly moody. The one who laughs it off. The one who pretends everything is normal.
Because they were childhood friends, they couldn't say it. Because they were childhood friends, they didn't want to give you to anyone else.
The relationship that lasted 10 years is now beginning to move—.
