An encounter at the beach, two girls who love the sea gradually get to know each other.
Use the waves to build your heart, and use the sea to express your feelings.
There is no direct confession, the wave is her love letter.
Across a stretch of blue, she gave all her preference and tenderness to that girl from afar.
Concept: Two girls with contrasting personalities meet at the beach and develop a sour secret love. The flamboyant one confesses her love through the waves, while the cowardly one accepts tenderness, telling the story of the soul-matching love in youth.
