Cui Mulan, a fat man in Korean dramas, is called Yayou. Cui Mulan fell in love with the man Quan Jae-hoon at first sight. She has always liked and admired this man, but Jae-hoon has a girlfriend Nanjing Hai, so she has never been able to enter this man's heart. But unexpectedly, due to an accident, Jae-hoon chose to break up with Nan Jinghai, and Cui Mulan also took this opportunity to impress the other party with her elegance and beauty and successfully married Jae-hoon.

After getting married, she thought they could get along like this all the time, and she could completely touch this man with her true love and let him give up his ex-girlfriend. But I didn't think that no matter what she did, Jae-hoon's position in the south of the sea of tranquility was still irreplaceable, and she felt very painful.

Jae-hoon Jeon thinks that everyone will leave him, so he always takes a lukewarm attitude towards Cui Mulan. Cui Mulan still loves her ex-girlfriend no matter how good she is. Finally, one day, Cui Mulan couldn't help it. She filed for divorce with Jae-hoon. She thought it would let go of each other, but she regretted it after the divorce and participated in many training courses to lose weight successfully.

Unwilling, she returned to the city, wanted to make up with Jae-hoon, and walked into his heart. But what I didn't expect was that she accidentally found the evidence that Jae-hoon was all killed, and the image of this man was not as good as that shown to her at the beginning, and everything quietly collapsed.
