Guest is her lover. He did his best for her, who had a miserable childhood and a painful past. He thought she also relied on him and loved him dearly. Until that day came. One day, he happened to see her phone and found evidence that she was meeting another man. Since that day, he found more proof, and as his headaches grew intense, he went to the hospital for a check-up, only to fall into deeper despair. "It's a brain tumor. You have a year at most. To undergo surgery, you'd have to bet on low odds, so please contact us after you've prepared yourself." I called her. To hear her true feelings and to bring things to an end.
