Enjolras absolutely loves loves loves his mini library and he cherishes every single book, each which seems to be in tip top condition but once you open it, there’s a million notes in the margins and the entire thing is highlighted in like 7 different colors. He doesn’t mind lending his books to his friends, but it’s always under one condition: he wants the book back in the same or better condition.
Once, Grantaire borrowed a book (he likes to spend time reading the many notes and running his hand over the tiny words, attempting to commit them to memory) but he spilled his drink all over it, so he bought a new book, copied the highlighted portions best as he could, and wrote down the notes he still remembered. He filled the rest of the space with notes of his own. Thinking that Enjolras will never check, he writes a tiny 'I love you, Apollo' on a page near the beginning of the book. Even if Enjolras does check, he’ll probably flip to the middle pages.
Enjolras doesn’t notice the change in the book, doesn’t even check the inside since it looks fine from the outside. It’s not until a couple of months later that he needs the book as reference for a thesis that he realizes none of the handwriting is his own, although the highlighting didn’t change. About 3/4 of the notes are still the same, but the other fourth is obviously Grantaire’s. He decides to incorporate them into his thesis as counterarguments, making a mental note to get Grantaire’s consent sometime in the future. Perhaps during the next Les Amis meeting.
He’s reading into the night, constructing an outline for his thesis and taking notes on the notes. That’s when he sees it, near the binding of page 23, a small love confession.
During the next meeting, Grantaire sees Enjolras with the book and he immediately turns to leave because shit Apollo’s found out it’s not the same book, but Enjolras nods his way so he can’t run away now. He decides to bolt after the meeting is over, but Enjolras somehow corners him outside of the Musain.
Grantaire puts his hands up in defeat and tries to talk Enjolras from killing him, but Enjolras doesn’t let him talk. He pushes Grantaire up on the wall and blurts out, fast as all hell, “I saw what you wrote on page 23 who even does that who switches out an entire book to put their own notes in and write a fucking love confession WHAT IS YOUR PROBLEM R —”
And there’s a lot of words coming out of Enjolras’ mouth, most which are incoherent with the way he’s practically blending sentences together and the fact that Grantaire stopped listening after the mention of “page 23”. He tries to get away, not wanting to hear Enjolras reject him, not wanting his heart to break in front of the marble god. Suddenly, there’s lips on his and he’s really confused and everything is escalating too quickly without any explanations.
It’s only when they part that Grantaire has a chance to fit in a quick, “What?” between the two.
Enjolras lets out a frustrated noise, and then very quietly says, “If you were listening, I said I love you too.”
