When Yu Bing learned that Zhang Chao couldn't find a good job because he had been in prison and could only rely on hard labor to earn money to support his sickly wife, she decided to let Zhang Chao be her bodyguard and driver.
After the two of them became familiar with each other, Yu Bing learned from Zhang Chao that in order to suppress his competitor, he had accidentally killed his competitor's blind sister.
Later on, because Zhang Chao turned himself in, he was sentenced to 20 years in prison. Because he actively cooperated with the reform in prison, he was released early.
Although many years had passed, he still couldn't forget that little girl from back then. Therefore, he scrimped and saved to donate the money he had saved to blind people, hoping to lessen his guilt.
Yu Bing recalled her previous life as she walked up the mountain. Since she could meet Zhang Chao so early in this life, Yu Bing hoped that she could change Zhang Chao's fate.
