Karl is allowed to live his past life and change it, this would grant him more years to live. Will it change it or make it worse? TW: Bullying, angst, mentions of suicide and the afterlife, slight yandere if you squint, manipulation, and swearing (if there's anything I didn't mention please message me so I can put it there) Time skips will be different chapters to avoid filler, also I'll add more characters as the story progresses. If you have any questions please ask!
