After I Was Reborn, I Caused My Best Friend’s Entire Family to Die

I'm in the Mood for a Fun Power Fantasy

I'm in the mood for feel-good stories. The lead can be an underdog or a strong female protagonist, either is fine. I've read too many unhinged stories lately, and I feel like my chest is all blocked up. I want stories where the male and female leads and even the minor villains can actually talk things out and behave like reasonable people, without dropping plot threads. Short stories are fine too.
