After being reborn as a cannon fodder mermaid, I was favored.

Yue Ling, a koi fish from the Jade Pool, transmigrated into a novel as a little mermaid adored by four male leads. The path home only opens when all four male leads reach a 100% affection level with her. To survive to the end and successfully return home, she has to outwit and outmaneuver them. The little mermaid, who initially thought she could simply pass the level and return home, unexpectedly falls in love with one of them during their interactions.
