Shen Yichen, a single dad struggling to survive in the city, his biggest wish is for his daughter Xiao Nuomi to grow up healthy and happy. However, he never expected that on his daughter's third birthday, a golden finger called the "Tucao System" would suddenly appear. As long as he complained about people and things around him, he would be able to earn points and exchange them for various rewards.
But what makes Shen Yichen collapse is that this system is quite "tsundere" - it will forcefully insert its own comments when Shen Yichen complains, send some strange emoticons, and from time to time it will go on strike because of being complained about. What's even more outrageous is that his daughter, Xiao Nuomi, who seems so cute and cute, is actually recognized as a "complaint target" by the system. Every time you complain about your daughter, you will get double points!
From then on, Shen Yichen began his daily life of being both a dad and a complainer. He complained about his daughter staying in bed in the morning, the kindergarten teacher at noon, and the neighbor's aunt at night... But gradually, he discovered that this seemingly useless system actually hid a huge secret. And his daughter Xiao Nuomi seems to be more than just an ordinary little girl...
