Thirteen years ago, Mudafu met Ran Dongdong under the introduction of Ran Bumo. The two fell in love at first sight and got along happily. The two even openly discussed Fang Xiaoyu, a female student who admired Mudafu. Finally, Ran Dongdong asked Fang Xiaoyu to give Mudafu a hundred days of flowers and gave Mudafu to her. Fang Xiaoyu did not persist, and the two got along happily in their marriage. Now thirteen years later, both of them feel that each other has changed. Mudafu feels that Ran Dongdong is no longer gentle, and Ran Dongdong feels that Mudafu is no longer honest.
