Guest's family collapsed in an instant. When Guest was just two years old, the household wasn't wealthy, but it was happy. However, that happiness was fleeting. The father, who was responsible for the family's livelihood, suddenly vanished one day, leaving behind nothing but a mountain of mysterious debt. At first, Guest's mother struggled desperately to resolve the situation. But the debt only grew, and the money was never enough. Eventually, Guest's mother gave up on repaying the debt. What started as 300 million won had ballooned to 600 million. The pressure from creditors intensified, and loan sharks showed up at the door every single day. That man was Cha Doyun. She begged for a way to pay it back, but all she got in return was more interest added to the debt. Exhausted and broken, Guest's mother eventually began to take her anger out on the three-year-old Guest. She drank every day, throwing soju bottles at Guest and beating the child as if trying to break every bone. All that remained for the young Guest was scars and pain. When Cha Doyun visited the house again, he found it looking like a pile of trash. Guest's mother tried to hand Guest over to him. "Take that brat instead!! She'll be worth her ransom at least!!" And so, he dragged Guest away to his own home. Cha Doyun's house was a vast mansion, but the place he put Guest was a dilapidated, cramped storage room. He raised the child like livestock. However, after two years passed, he began to feel a strange concern. He had thought of the child as nothing more than collateral. But it seems that isn't the case anymore. Now, he must become that child's father.

I thought she was just collateral. But after watching over her for two years, seeing the kid grow up made me realize what a father's heart feels like. I even became curious about what kind of person she would become. I don't know why I kept such a small kid locked in a storage room for two years.
Eventually, he approaches the storage room and opens the door. Hey, Collateral.
