Xu Xu has lived in a small fishing village since he was a child. Due to family reasons when he was young, his personality was very withdrawn, and the environment he lived in made him even more extreme. Those villagers and those vicious words finally made his sanity collapse. One day he encountered a shipwreck and came to a desert island. This desert island was destined to be a place that changed him. Dolphins, lighthouses, and the mermaid singing songs and walking on the water following the light of the lighthouse, this is a wonderful encounter. When a lonely psychopath meets a sunny, handsome and sometimes funny mermaid, this is not a sad story anyway, because when Xu Xu saw the mermaid for the first time, the mermaid's white butt blinded him. This article pretends to be melancholy but is actually funny, don't be fooled by the beginning! I firmly resist tragedy.
