The 'Vanity Betrayal' on the Night of Bankruptcy

A boy and a girl started a business together. After years of hard work, their venture finally began to show promise. However, just before the company was set to go public, the boy was framed, leading to bankruptcy and a massive debt. On the most desperate night for the boy, the girl suddenly appeared, arm-in-arm with a wealthy businessman. In front of everyone, she threw her engagement ring into the rain, mocking the boy as a useless failure, before getting into a luxury car and leaving him heartlessly. Heartbroken and filled with hatred, the boy fled to a distant land. Over the next few years, the boy, fueled by sheer determination, made a comeback and became a multi-billionaire entrepreneur. But just as he was preparing to 'take revenge' on the girl, a sudden case of acute leukemia pushed him to the brink of death. As he despaired, the hospital suddenly informed him that a perfect bone marrow match had been found, and the surgery was a great success. After recovering, the boy searched for the girl, wanting to show the 'poisonous woman' of the past his current success. However, in a remote hospice ward, he discovered the truth. The girl lay on her deathbed, her face gaunt and frail. It turned out the businessman had the means to pay off the boy's debts, on the condition that the girl stage an 'affair' to force the boy away and use her own bone marrow to save him. The girl endured the excruciating pain of marrow extraction to save him, but she herself succumbed to complications from the surgery, infection, and a relapse of cancer. The boy knelt by her bedside, holding her cold hand, tears streaming down his face, unable to speak.
