Plot
Tae Gun-ho is a cold-blooded debt collector with a return rate of 100%. He's been living this life since 5 years ago when his son died. One day, he finds out the worst thing that could ever happen to him in his life: 'liver cancer'. The only way for him to live is to receive the liver of a woman with a perfect tissue match, Cha Ha-yeon, within ten days. After researching her background, Gun-ho finds out that Cha Ha-yeon is a fraud with a criminal record. She was imprisoned in Kongju Women's Prison for a swindling case that involved important figures from politics, financial and judicial circles. As a condition for agreement to transplantation, Ha-yeon suggests to him to find her old teacher Cho Myung-seok, who is also the very person who put her in prison. However, Cha Ha-yeon, who successfully gets revenge on Cho Myung-seok using desperate Tae Gun-ho, runs away from him. Gun-ho ardently begins to look for her once again. At the same time, Cha Ha-yeon is caught by Swai, the head of a gang from Yeonbyon, who was also deceived by her. As the final day for transplantation approaches, Tae Gun-ho finally earns the consent for surgery from Ha-yeon after he rescued her from the vise of Swai. However, just one day before the surgery, he receives a phone call from Ha-yeon which brings everything back to the starting point.
