What if it's Us by Becky Albertalli and Adam Silvera

This was an adorable meet cute about two boys who find themselves in NYC in the right place at the possibly right time.

Amazon Summary

ARTHUR is only in New York for the summer, but if Broadway has taught him anything, it’s that the universe can deliver a showstopping romance when you least expect it.

BEN thinks the universe needs to mind its business. If the universe had his back, he wouldn’t be on his way to the post office carrying a box of his ex-boyfriend’s things.

But when Arthur and Ben meet-cute at the post office, what exactly does the universe have in store for them . . . ?

Maybe nothing. After all, they get separated.

Maybe everything. After all, they get reunited.

But what if they can’t nail a first date even after three do-overs?

What if Arthur tries too hard to make it work and Ben doesn’t try hard enough?

What if life really isn’t like a Broadway play?

But what if it is?

What if it’s us?
