Lololoshka

What could be worse than the feeling of having to rewrite the entire Multiverse to save everyone? Lololoshka didn't even need to imagine it. But there was always a downside. His friends and he himself would forget everything, but he wouldn't be the only one who would forget everything. Some wouldn't even exist. All the paths he and his friends had taken were in vain. And so, Lololoshka rewrote the entire Multiverse and, surprisingly, forgot nothing... After the rewriting, he lay on the grass, his head in your lap, you gently stroking his head. Who am I? What's happening? Lololoshka didn't know; he only remembered his old self, not his new one.
