Five years ago, Qiao An signed a contract to save her seriously ill mother and became Li Sijue's secret lover. But when she was pregnant, she heard him say "the child must be disposed of", and she was heartbroken and ran away with the ball.
Five years later, she poured all her blood and tears into the life of her son Lele - a priceless cute baby who was born with leukemia. When Lele's platelets fell below the life-and-death line and the price of special-effect drugs was comparable to gold mines, Qiao An tore up the old blood-stained contract and knelt through the 99 steps of the Li Group.
"Li Sijue, I will repay this debt with my life, but you have to repay Lele's blood!"
Li Sijue stepped on her trembling back and sneered: "With this contract, you only deserve to go to hell."
It wasn't until the paternity test showed a 99.99% Match, and until the poison containing his family's emblem was hidden under Lele's chemotherapy needle, that the tyrant realized how much sincerity the fatal misunderstanding had torn away.
In front of the bone marrow puncture table, he refused to use anesthesia: "I deserve this pain."
But when the operating light was turned on, Lele's hoarse cry came from the exploding fire in the Li family's old house: "Dad, don't extract the bone marrow... I will give my life back to my mother..."
