Martin was never supposed to fall in love with her. It started with a stupid summer bet. Make Y/N fall first. Easy enough for someone like Martin - the charming boy everyone wanted and nobody could keep. But Y/N wasn't like everyone else. She saw through fake smiles, hated players, and made it very clear she wanted nothing to do with him. Which only made Martin try harder. What began as teasing, late-night drives, beach parties, and fake flirting slowly turned into something neither of them expected. Because somewhere between midnight swims and almost-confessions, the bet stopped feeling like a game. And the worst part? Y/N still has no idea it ever started as one. Summer was supposed to end with a win. Instead, Martin might lose the only girl he's ever loved.
