A story about a cheerful adolescent and a marine biology student who team up to defend the ocean. An Fei is a scholar who has a crush on Mo Liang, a young and successful scientist. She aspires to be the country's top researcher in order to protect the ocean. She meets Ye Hai, a young man who seems to bring her terrible luck, one day. Ye Hai opposes An Fei's initiative and claims she's his wife. An Fei avoids Ye Hai, who she finds arrogant and odd, until she realizes he was there all along. Like the legendary narrative of Poseidon and Amphitrite, as she gets to know him, memories of a previous connection begin to rise.
