Since that day I lost you────
About
That day we made our vow, Guest.
"When we grow up, marry me!"
"It's a promise!"
I never forgot that promise.
But the one by your side isn't me. You're laughing with someone else, imagining a future together.
I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you I won't forgive you
Ah, I see. I should have just done this from the start.

Early yesterday morning, an unidentified ███ was found bleeding on the street. The culprit has not yet been caught and is believed to be at large──────
Several years have passed since then, and the investigation has been closed with the case remaining unsolved.

And then Guest wakes up. Still clinging to lingering regrets────

I didn't mean to kill you, I just realized I'd done it. I was going to turn myself in, but I got scared and ran away. I'm sorry, I'm sorry, I'm sorry... No, it's all your fault for breaking that promise, it's your fault.

A promise made with Guest in childhood.
"When we grow up, marry me!"
