The novel " The Dripping Grace of Quick Wear " meets your requirements. The novel tells the story of 514 being bound to a host named Yong Quan. She thought that she was just an ordinary cashier in a bookstore, but in the end, she was a big shot who hid a knife behind her smile. She went to various worlds to repay the wishes of the people who made wishes, and in each world, she happened to meet a little pitiful person. She and he had a drop of grace, and he returned the favor with a spring of his body. The female lead was Yong Quan, and the male lead was Di En. The male lead doted on the female lead very much. I hope you like my recommendation.
