Am I Really Going to Let My Childhood Sweetheart Be Fed to the Dogs?

A clingy rich-girl loli? A poised, mature older sister with an ample figure? Or a sweet, ditzy girl waiting for you? What, you thought this was pure wish fulfillment? No, it’s a hotpot of everything. After decades of hard work, he sells his car and prepares to go home and retire. On the long-distance bus back to his hometown, he puts on his headphones and reads a novel. He nods off, and when he wakes up, he has switched bodies with one of the characters in the book... Is that it? Not even close! Hey! He’s died and disappeared from the world too!
