I literally saw this prompt and thought of this idea immediately, lmao. The plot, the fic title, all of it. It was great.

There was a jokey theory floating around somewhere just after PMTOK released that posited that the reason Luigi was so chaotic/silly in that game was because he had the Chaos Heart in him influencing his actions to be, well, more chaotic. This is a theory I have been low-key obsessed with since reading it. I know that there are a variety of angsty directions this idea can go in, but — as boring as it is — to me the Chaos Heart is just, like. Domesticated. Just vibing in there, giving Luigi passive buffs like being able to survive things he shouldn’t sometimes. It does have a vested interest in its perfect host staying alive, after all.

This one took a whole lot of workshopping to get right, even if the idea was easy. The hardest part was figuring out how the Chaos Heart was going to manifest itself; i.e. how Luigi was going to get injured so that the Chaos Heart could inexplicably prevent all damage. After a few voice memos, I settled on Luigi getting hit by a car, and then everything else fell into place (e.g. what car? → a car in New Donk City → why are they there? → they’re there because of a referral)
