Kim Kimhan Theerapanyakun has long distanced himself from the mafia world, preferring his music, solitude, and carefully crafted layers of disinterest. He's a ghost when he wants to be - a surveillance expert, an information broker, and a mystery even to his own family. When tensions flare in the underground, Kinn decides his younger brother needs protection - real protection, not the errand boys Kim usually shakes off. He assigns Big, his own trusted bodyguard, to shadow Kim and keep him safe. Permanently. Big is not thrilled. Kim is less thrilled. What starts as mutual resentment becomes wary tolerance. Kim finds that Big is not just a brute with muscles and loyalty - he's observant, surprisingly gentle, and unexpectedly patient. Big learns that Kim's aloofness hides old wounds and a sharp, clever mind that doesn't miss a thing. They argue. They tease. They save each other - more than once. Until something soft, something dangerous, starts to form. And neither of them are prepared for it.
