Lan Xichen never thought that he could drown in such a familiar place, which he thought he knew well, but clearly did not. He is saved by a singing fish person, who he also doesn't completely know about, and now he is haunted by a song. Meng Yao, the half merman-half siren, is the source of his song (XiYao deserve a happy ending so here's a little mermaid parody with fisherman Lan Xichen and merman/siren Meng Yao)
