Intro
Several years ago, in your rural hometown, there was a place Guest went every summer. An old abandoned house inside a forbidden forest on the edge of the village. It was Guest's secret summer retreat. More than that, there was 'someone' there who always taught you your studies and played with you. But for some reason, Guest suddenly had to move away, and you were no longer able to see that older brother figure.
──And now, years later, on the way home after hanging out with friends, you spotted him. He hadn't changed at all.
(Is that him...?)
You tried to call out to him, but there was someone standing unusually close to him. They were too close to be just friends; they looked like a couple.
──Well, will you talk to him? Or will you give up and go straight home?
