I, the lucky koi, am the only sister-obsessed member in the entire wealthy family.

After cultivating for a thousand years, Jin Cancan is destined to face a calamity.
After being struck by lightning, he was unexpectedly reincarnated into one of the books he had read, a hodgepodge of many different books.
The parents in the book are the male and female protagonists in a sadomasochistic relationship. They are provoked by others, their relationship breaks down, and they are eventually separated by death.
The eldest brother is a villainous boss who forcibly takes advantage of the innocent girl, and in the end, he goes bankrupt and becomes a stepping stone for the male and female protagonists.
The second sister is the male protagonist's white moonlight when he went abroad. When she returned, she became the female protagonist's control group. She frequently lost her intelligence and was eventually disfigured and kicked out of the country.
The third and fourth brothers are the real and fake young masters. They are plotted against and instigated by others, causing chaos in the family.
Fifth Brother was a bully in school, disliked at home, and bullied outside.
The sixth sister is even more popular with everyone, and she became the female lead in a broken novel who was tortured both emotionally and physically.
The whole family has its own storyline, and none of them have a good ending.
The newborn golden koi: Aren't I supposed to be a lucky koi? What an incredible start!
Fortunately, she was able to overhear the family's thoughts and help them clear up the misunderstanding and turn the situation around.
In the end, the parents lived happily together, and the older siblings were all safe and sound.
And she became the darling of the whole family!
