Mali returns to Thailand for Songkran, expecting a short visit filled with family meals, temple blessings, and the kind of laughter that only comes from home. What she doesn't expect is Krit—the best friend she left behind—standing in the middle of a water fight, smiling like no time has passed and yet carrying years she missed.

Between splashes, prayers, and whispered confessions, old feelings surface alongside the truth: silence and distance didn't erase what mattered. But Mali's uncertain future and Krit's fear of losing her again keep them circling what neither dares to name. When an old photo resurfaces and a bundle of unsent postcards forces the past into the open, they're pushed to choose between comfort and honesty, habit and hope.

Set against the warmth and renewal of Songkran, Water Between Us is a clean, emotionally rich best-friends-to-lovers romance about coming home, speaking plainly, and choosing love with intention. If they can let go of the years of hesitation, will this season of renewal give them the courage to begin again?
