Lin Wan worked as a perfect substitute for three years until his Bai Yueguang returned to China. She donated her eyes, health, and even part of her liver. The final diagnosis of terminal gastric cancer became the straw that broke her back. She signed the divorce agreement and disappeared completely.
Lu Jingchuan thought she was just having a tantrum, but found that she had already paid off all her "debts" and the only gift he gave her had never been opened. He searched frantically, but what he finally found was her back at the end of her life, leaning against someone else and looking at the starry sky. This farewell will last forever.
