After the Young Master from a Really Wealthy Family Was Bound to the Cancer System, the Whole Family Collapsed

My name is Xiaonan, and I am bound to the sick time travel system. The system stuffed me into the body of Pei Zenan, the real young master of a wealthy family, a poor man who was also gnawed by stomach cancer and rejected by his loved ones. This family regards the fake young master who was carefully raised as a treasure, but they are only defensive and cold towards my lost and found biological son. The third sister's hot curry splashed on the noodles, the neglect of my parents, the hypocrisy and frame-up of the fake young master... I was like a rat in the gutter, even breathing was wrong. I am used to pain, and the stomach cancer in my previous life made me fearless of death. The body was deteriorating at an accelerated pace, and coughing up blood and severe pain were always present. I silently bought painkillers and waited quietly for death. Only Su Yihuan, the tough-talking and soft-hearted lady, stubbornly gave me milk, saw through my illness, and clumsily tried to save me. The warmth she gave was like light shining into an abyss. My terminal illness was not revealed until I was put in the equipment room and received emergency treatment. My second sister discovered the diary I hid under my pillow - those were the eighteen years when no one cared about me, the coldness of the orphanage, the longing for family affection, the trampled sincerity, and the last sentence "I miss my grandma." The truth tore apart the pretense: Pei Jiachen's viciousness, his father's selfishness, and the family's belated regret. They broke down and begged for forgiveness. But it's too late. My last strength was just enough to say "I like" Su Yihuan in my grandma's old house. My name is Xiao Nan. After two lifetimes of illness and loneliness, I can finally go to my grandma. This wealthy family, these belated tears, have nothing to do with me after all.
