I struggled for twelve years to support my sister through her PhD, but in the end, it was exchanged for a single sentence: "I don't know him." When our parents passed away, Shen Zheng was only eighteen. For his sister, he gave up his own future, working day and night to move cargo. Who would have thought that after graduating with her PhD, she would look down on him for being uncultured and useless, actually cutting ties with him in front of everyone. Shen Zheng's heart completely turned cold; he would no longer play the fool. The house, the car, every account that needed to be settled was calculated clearly. But when the truth was exposed and his sister was taught a harsh lesson by reality, crying and begging her older brother for forgiveness, could everything ever return to the way it was before?
