Chloe, a top urologist and secretly the heiress of a medical dynasty, is known for helping men “get back in the game.” William, the CEO of a food delivery app, goes undercover as a delivery guy and accidentally ends up in Chloe’s clinic—where she mistakes him for a patient with erectile dysfunction. To dodge an arranged marriage, Chloe strikes a deal: free treatment in exchange for a contract marriage. Little does she know, William is actually her father’s ideal son-in-law. As they start living together, Chloe earnestly begins his “therapy,” while William hides the fact that he’s perfectly fine. Amid close calls and concealed identities, their sweet, slow-burn romance begins to blossom.
