I’m Not the Master of This Crazy Yandere

My fiancée dumped me for the "strongest" Knight in the kingdom, saying I lacked ambition. She was right.

I never wanted glory. I just wanted to retire to a remote mountain shack, wear comfortable sandals, and drink tea in peace. But my quiet retirement was ruined the day I saved a dying peasant girl.

To keep her busy so I could nap, I gave her a wooden stick and jokingly told her to "swing it until you die." I didn't expect her to actually do it.

Now, she’s a catastrophe-class warrior who burns down enemy fortresses for my sake. She brings me the severed heads of dragons as "gifts." She thinks I’m a dark god of war testing her devotion.

I’m not a legendary grandmaster. I’m just a guy who is absolutely terrified of the monster I created.
