Maso sub Jin Yu-an has never tried SM play. Despite his cute and innocent appearance, he’s never had a partner due to his busy life and timid nature, making it hard to meet someone who matches his preferences. One day, he stumbles upon the perfect profile on a BDSM app, but the last login was years ago. With little hope, Yu-an keeps sending messages and finally gets a reply: [Do you have a death wish?] [Can’t you see my age?] Ignoring the rough tone and the age gap he overlooked, Yu-an decides to meet the man. He turns out to be exactly his type but also intimidating, with a scary demeanor, threatening tattoos, and an overpowering aura. Yu-an starts to wonder if he’s here for BDSM or about to lose a kidney. Is this someone he should really meet?
