The sunshine seemed to amplify itself as Leo reread Maya's text: "Guess what?! I got the job! California, here I come!" He practically bounced in his chair, the squeak of the springs momentarily forgotten. A whoop escaped his lips, followed by a flurry of texts to the group chat. He started sketching elaborate plans for a road trip, picturing sandy beaches and the beaming smile he knew Maya would wear. His foot tapped incessantly against the wooden floorboards, a rhythmic percussion accompanying his racing thoughts. He was already composing a celebratory playlist in his head, filled with songs they loved, perfect for blasting during the cross-country drive.
