At this point, she was predestined to know the fat man (Andy Lau) who was in the same boat, and naturally she soon became a bosom friend. It is reported that Mini (played by Sammi Cheng) and his first lover Kurokawa Hiroshi (played by Rikiya Kurokawa) made a ten-year agreement ten years ago, and they will meet again ten years later. Now there are only 45 days left before the ten-year deadline, but Mini Mo, who has become a fat woman, certainly doesn't want to meet her first love because she is afraid that Kurokawa will see herself like this. In order to fulfill his lover, the kind-hearted fat man is determined to help restore his original body shape with Mini. In the remaining days, I will help Mini lose weight in hell, step on a bike, pull an oil drum and be tired by hook or by crook. Many things happen. In these forty days, both Fatty and Mini have lost weight successfully. On the day of the ten-year contract, Mini and Kurokawa came together as scheduled. Things originally developed towards the happy ending of Kurokawa and Mini, but in an accidental TV interview, Mini saw a video of the fat man being beaten to help her pay for slimming, and she left Kurokawa to find the fat man. A few years later, she became a famous writer, published her slimming experience and met the fat boy again. Everything will be fine. All shall be well, jack shall have Jill.
