Who is in charge of my youth? Why does Yu Fang live in prison?

Yu Fang was jailed for helping Lao Li (the owner of the automobile maintenance department) to modify vehicles of unknown origin, and was finally arrested on the charge of stealing and selling vehicles. So I went to prison. I owe 0.2 million/200 thousand because when he eloped with Xiao Yang, he accidentally knocked Xiao Yang's father's money to the ground, which led to the dislocation of the second and third vertebrae where the money came in. The medical expenses amounted to 670,000 yuan, and Xiao Yang's mother couldn't compensate him so much when she looked at his house, so she only asked him to give him100,000 yuan in the bank card, but because he loved Xiao Yang too much, he felt sorry for Xiao Yang's father, so he insisted on being responsible for Xiao Yang's father to the end. At that time, Lao Li watched him every day.
