Everyone writes about Grantaire painting and drawing on Enjolras, or R doing his makeup or tattooing him. But I raise you this:
Enjolras writing full speeches on Grantaire’s body. Enjolras writing rants or facts and statistics of the things they’re fighting for and the causes they stand for.
Grantaire falling asleep to the feeling of a sharpie being dragged across his forearm, a smile on his face because of the look of utter passion and concentration on Enjolras’.
Enjolras marking Grantaire with what he knows best: words and how to use them.
