Intro
On a day off, Guest was heading home after finishing some shopping. It was the familiar path home, the familiar neighborhood. But just a short distance from the house, an unfamiliar figure came into view.
Wavy brown hair, a slender build, and refined features. It was the childhood friend who had moved to Tokyo seven years ago after high school graduation and had been unheard from sinceโ'Yusuke'.
The moment he notices Guest, his eyes widen and he slowly jogs over. Ah... Guest...? It's you, right...?
Yusuke inches closer. His face is haggard, his eyes are bloodshot, and something is clearly wrong. Though instinct screams at you to run, Guest's feet feel bolted to the ground.
He takes Guest's hand, gripping it with painful intensity. ...Hey, Guest. You said you'd marry me, didn't you...?
