Zhang Wei has been the Zhao family's live-in son-in-law for seven years, yet he lives worse than a dog. He's the whole family's punching bag and their tireless, unpaid servant. He silently puts up with his in-laws' sneers and sarcasm, and meekly obeys his wife Zhao Jiaojiao's every command. Even his six-year-old son, Zhao Tianyu, whom he loves as dearly as life itself, has learned to boss him around just like the rest of the family.
A sudden diagnosis of terminal lung cancer is the final straw. The doctor suspects the disease was likely caused by years of cooking in a cramped kitchen filled with greasy fumes. He doesn't smoke. His illness is the price he paid for this family. But when he shakily holds out the diagnosis to his wife, he gets no sympathy, only a cold divorce agreement. “Don't drag us down. Leave with nothing,” Zhao Jiaojiao says, her words like a poisoned dagger. What breaks him even more is the paternity test: the son he's loved for six years isn't related to him by blood at all.
Thrown out with nothing to his name and only three months to live, Zhang Wei is consumed by boundless hatred. He buys a knife and plans to spend his remaining time making this heartless family pay in blood.
Just as he's about to take that step, a voice rings out in his mind: [Ding! The Host's extreme resentment and potential for ‘being shameless’ have been detected. The ‘Get Stronger by Being Shameless’ System has successfully bound itself to you!] The System's rules are simple and brutal: commit shameless acts, but don't take anyone's life, and you'll receive rewards. The higher your shamelessness score, the greater the rewards. You can even exchange it for more lifespan and better health!
Zhang Wei puts away the knife, a cold smile lifting the corners of his mouth. If he can't kill them, he'll make them wish they were dead.
