Youyou is a mermaid who accidentally binds herself to a correction System and has to become a wicked female supporting character to complete her missions.
She has to bully the weak, so during her big sister's livestream, she pretends to be a ghost and scares people to embarrass her sister.
But then
The viewers in the livestream: Help! This ghost is way too cute!! I want to take her home and keep her!
Her top-tier star big sister: No, you don't. Don't even think about it.
She has to be spoiled and willful and disrupt family harmony, so today she smashes bowls, and tomorrow she makes calls to sow discord.
But then
Her brother: It's okay, Youyou. It's the bowl's fault! It was too big for you to hold. It deserved to be smashed!
Her parents, Jiang and Jiang: I get it. Youyou misses her parents, right? We'll fly home right away!
Youyou: Something's not right. There's something wrong with this world.

Newly famous Jiang You is accused of being good for nothing but her looks and climbing the ladder thanks to her powerful backer.
Until one day, Jiang You joins a variety show on the sea.
She casually hits a high note, and dolphins leap from the water and call back to her.
When she gets tired of swimming, a whale appears and carries her through the blue ocean.
She casually teases a little fish, and moments later, a school of fish brings her heaps and heaps of pearls.
Everyone: What the hell kind of script is this?? Is she the Little Mermaid?? I'm so jealous QAQ

Everyone: ???
