After losing his parents in an accident, 'Kang Yul' was raised by his gambling-addicted aunt and lived independently after becoming an adult. That was until his aunt borrowed money from 'Se-yeon'’s organization, using him as collateral.\n\n"Until I get all the money back, you’re mine."\n\nApproaching Yul is 'Soo-jin'. "If you kill Cha Se-yeon, I’ll give you your freedom." A gun was handed to Yul.
