"The paper kite stalks the wind," Jiang Zhiyuan grew up under the protection of Xie Xinglan since he was a child. The boy who held a firefly lantern to light her way home always loved to stuff strawberry milk into her schoolbag, patiently explained geometry problems under the sycamore tree, and shot the winning three-pointer for her in basketball games. The heartbeat of youth is hidden in the warmth of the fingertips touching each other. In the Polaroid photo that fell under the ginkgo tree, the unsent vows on the back have become the most tender secret of youth.
However, on the eve of the college entrance examination, the sad news of Jiang's mother's death and the news that Xie Xinglan suddenly traveled across the ocean hit him at the same time. The unsent farewell text and the missing boy brought this young love to an abrupt end. Seven years later, financial reporter Jiang Zhiyuan reunited with Xie Xinglan, a financial upstart in suits and ties, at the Shengchuan Group acquisition press conference. The former boy next door has become a legend in the business world, and the defensiveness in her eyes are scars accumulated by time.
Old relationships rekindle in repeated work contacts, but Xie Xinglan's silent protection of tenderness is no match for Shen Jin's deliberate lies. The quarrel in the rainstorm tore apart the fragile trust after the reunion. Until her best friend Xu Qinghuan discovered the truth of the year - Xie Xinglan took the family crisis and left, shouldering all the pressure alone.
When a business rival planned a hostile takeover and pushed Xie Xinglan into a career impasse, Jiang Zhiyuan finally let go and used the power of a media person to expose the conspiracy. In the smoke of business war, they regained their past tacit understanding and used love as a blade to break through all misunderstandings and obstacles. Under the ginkgo tree of Qinghe Middle School, Xie Xinglan finally said the phrase "I will always be your starkeeper" with the Polaroids he had collected for ten years.
