When an unattractive male classmate meets a serious female class monitor, he sings Eason Chan's "Ten Years" to her, and they become the most familiar strangers ten years later; when a slovenly cast steel worker meets a fledgling trainee lawyer, she returns him a piece of expired chocolate, which leads to a thrilling reunion. This is a story about a pair of childhood sweethearts that lasted for more than 20 years. The story comes from life but is different from life. It reproduces a vivid life with laughter, tears and flesh and blood. Uh, okay, this is actually a sweet story about a rough guy and his first love who finally come to fruition!
