Ko Woon-Ha lives in constant pursuit of stimulation, yet his dulled senses leave him unable to truly feel pain, let alone pleasure. That changes after a single night with Cha Gyu-Won, the younger brother of his FWB, when Woon-Ha is able to experience genuine desire for the first time in his life. The problem is, Gyu-Won is everything Woon-Ha claims to despise: younger, inexperienced, and sworn to remain chaste until marriage, he seems to cling to a naive fantasy of a first love that will last forever. Convinced he’s made the worst possible mistake, Woon-Ha tries to brush it off as nothing more than a lapse in judgment…until the reality of his situation hits him harder than he though possible: Gyu-Won might be the only one who can make him feel anything - both physically and emotionally.
