Growing up rich meant Jungkook could do whatever he wanted. Including breaking the pride of a quiet boy whose mother worked in his house. Years later, Taehyung appears in Jungkook's life again-different, colder, and impossible to ignore. Jungkook doesn't recognize him. Taehyung does. And this time, the servant's son isn't here to obey. He's here to make the pretty boy regret everything.

Twenty-one-year-old Taehyung is desperate-working multiple jobs, studying IT, and raising his sick younger brother alone, he makes a reckless decision to hack a wealthy stranger's account, planning to return the money later. But the account belongs to Jeon Jungkook, a cold-hearted CEO who secretly runs a mafia empire, and when he discovers the breach, he's not just furious-he's intrigued by the struggling college student who somehow broke through his system. Jungkook inserts himself into Taehyung's life as punishment, but the hunter never expected to fall for his prey but fate had plans for them "Come here." "Please... stay away from me." "Don't make me ask twice." "I was going to return the money-" "Fight me if you want." "Just let me go..." "The leash stays either way." "Why are you doing this?" "Question is... you on your knees, or closer to my lips?"

Taehyung has always survived on his own-scholarship student, quiet, careful, and burdened with a sick mother he can't afford to lose. University should be a chance for freedom, but the world he enters is filled with wealth, cruelty, and eyes that linger too long. Jeongguk is everything Taehyung is not: rich, untouchable, and dangerously perceptive. The moment their paths cross, a quiet, almost invisible war begins-Jeongguk doesn't want him, yet he doesn't want anyone else near him. Observed, tested, threatened, Taehyung must navigate a predator cloaked in charm and smoke, all while protecting what he loves most. Jeongguk learns that even monsters can crave warmth. Because some salvations come with teeth. And some mercies are crueler than hate. "𝐻𝑖𝑠 𝑚𝑒𝑟𝑐𝑦 𝑤𝑎𝑠 𝑡ℎ𝑒 𝑐𝑟𝑢𝑒𝑙𝑒𝑠𝑡 𝑡ℎ𝑖𝑛𝑔 ℎ𝑒 𝑒𝑣𝑒𝑟 𝑔𝑎𝑣𝑒 𝑚𝑒." ≿━━━━༺❀༻━━━━≾ ⟰Jeongguk ⟱Taehyung

Jimin: (trembling, his voice a whisper) Tr... trust me... hyung... I didn't... Taehyung: (his eyes blazing with anger) DON'T DARE TO CALL ME HYUNG! YOU ARE NO ONE TO ME! Jk: I Don't hate you.. But don't love you either... Jungkook: (frowning in confusion) But hyung, she's a stepsister, and Jimin is our brother by blood. How could we trust someone else's word over his? Something is wrong... . . .
