Lev keeps thinking that this is it, there is no way he could possibly fall more in love with Sasha, and then he does.
He learns about why you shouldn't say abstract art could be done by a two-year-old (although he is still privately suspicious that many of the pieces could be done by a competent interior designer). They go for long walks through Central Park and snuggle and have a picnic. He does not succeed in his argument that they should go to the store full of M&Ms. He's fine about not doing that again on a plane but he definitely gives Sasha as many orgasms as possible some other times. (It usually doesn't make Lev come.)
He has someone to talk to about books and movies. He eats the things Sasha bakes. He climbs trees with Sasha. They go on walks. They travel.
It makes him feel so so happy whenever Sasha smiles.
Lev tells Sasha that he should definitely go back to school and major in art history. He is happy that in a few months Sasha is going to be able to do whatever he wants.
He never liked art much before. He won't lose that much once Sasha leaves.
They have kind of a lot of sex. Lev tries to remember Sasha's face, his hands, his genitals, to fix them in his mind for once Sasha is gone. He feels guilty about making Sasha look at him but it's so nice to rest his chest against Sasha's back that he does it anyway sometimes.
Sometimes Lev goes hours, or even a day, thinking that he has a boyfriend whom he's in love with, and they can make plans for the future and have stupid injokes and they don't have to rush to fit anything in because they are going to be together forever-- if they don't see the movie this week, no big deal, they have years-- and he'll never have to fall asleep without Sasha in his arms ever again.
