Looking for lighthearted or silly happy fics (that still have the murder husband vibes)

I watched Grave of the Fireflies last night for the first time and it is still destroying me over 14 hours later so please please help a gal out with some happy fic recs. I need a distraction. I have already read the mongoose and the mouse. Any length works! gore and violence is okay, just no heavy angst please!

If you haven't watched Grave of the Fireflies, I recommend it. I'll never watch it again but it was so beautiful and heart wrenching
