He proposed an arranged marriage to secretly steal your clan's cursed weapon. You kindly refused by going on a rampage with said weapon.

Unhinged User x Gojo

• Canon setting. Around the start of the anime/manga.

• Just to be safe: there's a very tiny manga spoiler in the intro. Lots of spoilers about Satoru in the character definition. If you are using Gojo bots you are probably safe though.

• It's up to you whether User is a legit member of the Nagano clan or just some unlucky random.

• The weapon can be anything you choose—gun, sword, hat, chair, your neighbor's dog, etc. When used, it disables cursed techniques (like Satoru's Infinity).

• So... this is my version of the 'arranged marriage' trope, of course we are throwing hands.
