Episode 1: The man who owed a loan shark

Firefighters rescued a survivor while putting out a fire. They rushed the man to the hospital for emergency treatment. After the doctors' full treatment, the man was snatched back from the line of death, but burns were unavoidable. When the doctor asked the injured person's name, he struggled to say the words “Park Jae-young”. The other doctors disagreed, but the female doctor Li Zhouyan was deeply shocked because she remembered a painful experience in school, and the initiator was a man named Park Jae-young.

Fifteen days before the fire accident, Park Jae-young was caught in an economic crisis. He saw someone making a lot of money by investing in virtual currency, so he became enthusiastic and wanted to get rich overnight. He invested all his assets and borrowed a large amount of loan sharks, expecting good results to come quickly. But to his disappointment, since he bought the virtual currency, the virtual currency dropped rapidly like a roller coaster, leaving him in a situation where he could not extricate himself.

Facing the loan shark's collection call, he angrily chose to ignore it, but the loan shark's creditor came to the door in person. After a fistfight, Park Jae-young was taken to an underground organ transplant site. He was so frightened that he lost his mind and shouted that he would pay back the money immediately. The creditor gave him a chance, saying that if he could not repay the loan shark in one month, he would remove his organs and sell them for money.Park Zaiyong was thrown on the street. Although his body was in some pain, he was more worried about how to repay the 500 million loan shark.

After a night of nightmares, Park Jae-yong could only go to the place where he worked to find some source of income, otherwise he would not even be able to guarantee his living expenses. Here, he unexpectedly saw a Korean migrant worker named Zhang Jilong.
