" What if there’s a do-over down the line for us? What if we end up in the same city again and pick up where we left off? What if we go as far as we once hoped we would, and boom, happy ending for us? But what if this is it for us? What if we never get to kiss again? What if we’re there for each other’s big moments, but we aren’t at the heart of those big moments anymore? What if the universe always wanted us to meet and stay in each other’s lives forever as best friends? What if we rewrite everything we expect from happy endings?
Or…
What if we haven’t seen the best us yet? "
