Synopsis：Li Chang and Xia Xiaoxue are childhood sweethearts. As they grow up, Xiaoxue gets into a prestigious university, while Li Chang fails the college entrance exam. He works desperately, going out to sea to fish, but an accident leaves him injured and with amnesia. Upon hearing the news, Xiaoxue drops out of school to care for him, but her parents strongly oppose it, even threatening suicide to force her to marry someone far away. On the day of Xiaoxue's wedding, Li Chang regains his memory but loses the one he loves most. After Xiaoxue is married, Li Chang reluctantly accepts Yuan Yuan, a girl who has always liked him—only to discover that Yuan Yuan is his biological sister. Unable to bear this truth, Li Chang jumps into the sea to commit suicide. Knowing this, Xiaoxue walks into the depths of the ocean.
