It's All Black Stocking's Fault

Liu Mang, now 30 years old, was a good student in the past. But his life wasn't good anymore. One day, when he was massaging his boss' legs, he fainted and went back to the time he was 17 years old. Knowing that studying hard would be useless, he decided to change his fate, and do things he'd never dare to try in the past. Credits to：圣诞文学网
