My stomach flutters with butterflies of hope. It warms my chest and pains my heart because a part of me knows it’s just a dream. But hope is gleaming in Billie’s eyes right now, and I grin back at her. “Oh, oh, I know!” she exclaims. “We can go on the bullet train! Oh my god, that would be crazy.” Her delighted voice makes my entire body feel light. I love her, and I want nothing but the best for her.
