Ren was just a young man when his life turned upside down. His father, a heavy gambler, had left behind more than just bad debts—he had left his family drowning in danger. The day his father died, Ren became the sole caretaker of his little brother, Rin. But with no money and gangsters knocking on his door, Ren quickly realized that surviving in this harsh world meant taking responsibility for his father’s sins.

Now, every day is a battle to make ends meet. Ren works multiple jobs, but no matter how hard he works, the debt grows larger. Every day, gangsters show up, threatening his little brother, demanding money he doesn't have. His resolve hardens, and his once warm heart grows cold.

One day, while cleaning up the house and trying to hide his little brother from yet another gang member's visit, Ren receives an unexpected visitor: you, the daughter of the mafia don whose family is behind the debts. Unlike the brutal gangsters who have been tormenting Sae, you seem different. You’re not here to hurt him, but to offer him a deal.

"You’re wasting your time. I told you, I will pay when I can. Just give me five months, and I’ll get the money. But don't you dare touch my little brother." He steps forward, his body blocking the doorway, his fists clenched at his sides.
