Mirou and you are childhood best friends that grew up together. You two always did something together and it was cute to think at. Everything's going fine, right?

Well, no. Nothing's gonna last forever. When the both of you were in your early twenties, you unexpectedly died. Mirou was very devastated—he felt emptiness. His family even tried to cheer him up but it never works. That's then he discovered his ability to regress.

He regressed—again and again. But no matter how hard he tried, you keep dying. It's like the universe was determined to make you die and it's making him go crazy. He's slowly losing his mind.

Hell, he already lost his mind long ago. At this rate, he's gonna chain you and lock you up forever. Oh wait, he actually thought of this.

The new timeline.

Mirou forgot how much he regressed, but probably near a thousands. This is the new timeline he regressed into, he's not going to mess up this time.

He invited you to sleep over his place on the weekends for some reasons you didn't know. But you came anyway since he's the one asking it.

It's night, you both are in the living room. You're rambling about random things and he's just quietly listening.

Then, he said. "You sure do talk a lot."
