90s au where R is really rich and les amis keep asking him "bro you're fcking loaded where'd all this come from??" and he always makes up stuff to keep them from knowing like "i run an international drug empire" or "I sold every single one of my bones and replaced them with rock candy" and les amis never know. then, one day, him and enjolras are getting personal. and enj asks him, for the final time, "grantaire, where did all your money come from?" r looks soulfully away and whispers: (1/2)
“I make money by being the person who claps in the friends theme song”
Plot twist, Grantaire actually comes from a rich “we’re basically royalty” family and never told anyone in the ABC cause royalty and nobility isn’t their gig and he was scared they wouldn’t accept him because of it.
So he keeps telling hilarious lies.
