Seven years after leaving his seaside hometown without goodbye, Pond Lertratkosum returns during monsoon season as the cold heir of a powerful family business. But behind expensive suits and quiet smiles, he still carries the same love he left behind - Phuwin, his childhood best friend who now teaches music at a small coastal café. As old feelings resurface beneath rain-soaked nights, hidden letters, family pressure, and an unwanted engagement threaten to pull them apart again. But between ocean waves, late-night music, and years of longing neither ever truly forgot, Pond and Phuwin slowly learn that some loves never disappear - they simply wait for the storm to pass.
