The ink on the divorce papers is barely dry when An Ning heads for the beaches of Kenting, carrying with her the deadlock in her startup project. In the salty sea breeze, she meets a man with a “Y” carved into his drumstick: A Zuo, drummer for the band Xing Zhou. To her surprise, she also catches the eye of the band's lead singer, Ke Yan.
The frontman of the band that had accompanied her through her youth is now crouched on the rocks, adjusting his rhythm, oblivious as the waves soak his trouser legs. A bonfire party and a few casual remarks about off-the-beaten-path destinations bring warmth to the tourism app proposal tucked away on her computer, and stir ripples in her frozen heart.
From sunrise at a Kenting lighthouse to the neon-lit night markets of Taipei, from late-night overtime in Beijing to the sea of glow sticks at the Bird's Nest, she is a startup founder frazzled by fundraising, while he is a musician who lives beneath the spotlight. The gap in their ages, their different lives, the distance across the strait, and the pasts they have both kept buried all stand in the way of their relationship.
When rumors spread and an unexpected pregnancy throws all their plans into disarray, they finally understand: love is no shelter from the storm. It is the courage to face the storm together when waves crash against the strings. The feelings hidden in song lyrics and the journeys made across mountains and seas will at last find their most moving echo in the stars shining on their marriage certificate and the cry of their newborn.
