After Rebirth, the Younger Brother Became a Maniac Who Doted on His Sister.

Before Yu Nian was reborn, his family favored sons over daughters. Before his death, he learned that he had mid-stage gastric cancer that could be cured, but his parents cruelly took away the life-saving money. When he woke up, he found that he was reborn? The family's attitude towards him and his attitude in his previous life have actually changed, and his cruel brother suddenly became a maniac who dotes on his sister! Along the way, I learned that my rebirth was not God's blessing, but someone's sacrifice as a price. This time Yu Nian will only cherish those who are kind to her, and will never rip out her heart and lungs again!
