In order to save her mother's life, Lin Nuonuo was forced to marry Gu Yan, a technology upstart, to pay off her debts and signed a three-year "tool man" agreement - to be his invisible wife during the day and his physiological needs machine at night. He treats her as trash and worships Bai Yueguang as a god, but he doesn't know that the stockings he tears to pieces every month and the impatient gasps he draws are drawn by her in "Observation Notes of a Scumbag" and become a hit comic with millions of views. She earned a million a year by being "scumbag", saved 267 vests and paid off her debts. On the day of the divorce, she maxed out his card and took advantage of the loophole in the agreement: "I slept with her 300 times in three years, and the interest will be deducted from the market value of your company." Her ex-husband broke down and chased his wife, but found that she was actually the top designer "Nuomi Dumpling" she was looking for, and his company's popular APP were all sketches she drew before the divorce. What's even worse is that he can't even add her trumpet. In this crematorium of chasing his wife, it is not her who is burned, but his entire business empire.
