Mammon and the beast (On Hold For A Bit)

When someone spreads rumors of diavolo and mammon dating and getting married.

They have to play the part until this is all taken care of.

And at first mammon doesn't care but soon it starts dwelling on him and he starts feeling used.

And slowly he starts going on a downward spiral as he's stuck in a marriage he doesn't want to be in.

Will everything work out in the end? Will there be a happily ever after?.

Idk but this idea sounds like that dark theory of beauty and the beast...
