Bu, a romantic young woman from Taiwan, stumbles upon a message in a bottle while swimming at the beach. The message, seemingly a love note, piques her curiosity and inspires her to travel to Hong Kong in search of the person who wrote it. Upon her arrival, she discovers that the message was originally intended for a different girl by a businessman named Albert. Despite not being the intended recipient, Bu finds herself enchanted by Hong Kong and decides to stay temporarily. As she explores the vibrant city, Bu unexpectedly crosses paths with Chi Wu, a successful businessman known for his incredible martial arts skills. Their first encounter is serendipitous but leaves a lasting impression on both.

During her extended stay in Hong Kong, Bu becomes involved in the lively and sometimes chaotic world surrounding Chi Wu. Meanwhile, a playful rivalry emerges between Chi Wu and his business competitor, L.W. Lo, adding further complexity to Bu's new life in the city. While Chi Wu constantly finds himself engulfed in quirky challenges and comical situations, he can't help but be intrigued by Bu's vivacious spirit and unwavering determination. As Bu continues her adventure, she gets pulled into Chi Wu's whirlwind lifestyle, filled with unexpected friendships, light-hearted escapades, and a budding romance. However, beneath the comedic surface is the looming question of whether Bu will find what she truly seeks or return home unfulfilled.
