Anime Crossover: Turns Out I’m the Doomed White Moonlight in Their Lives

I found myself in an anime crossover world and got a [Life Simulator]. Each time I run a simulation, I become someone with a different identity. I could be a student, a teacher, a passerby, or even a stranger. I thought I was just experiencing different lives over and over. That is, until the simulations ended. Only then did I realize The boy who saved Shizuka Hiratsuka on the rooftop became someone she would never forget for the rest of her life. The person who helped Eri Sawamura escape her loneliness never appeared again. The person who changed Utaha Kasumigaoka's life as a writer seemed never to have existed. … As reality and the simulations began to overlap, everyone was searching for the same person. And only then did I finally understand. I'd already become the unforgettable first love in their lives, the one who would never return. (No main storyline; the original plot is only a reference. New readers are welcome. If you think it's too padded, don't read. Simulator theme.)
