Do Hye-ju is a lifelong singleton juggling two jobs — office worker by day, adult web novel writer by night. When her secret serialization gets discovered by director Han Jung-woo, she's fired on the spot. But when the company realizes they can't do without her, Jung-woo offers to rehire her — and this time, Hye-ju holds all the cards. "Director Han, I want you to be my adult scene consultant." And just like that, their steamy coaching sessions begin. There's just one clause in the contract: "If either party develops real feelings, the contract is immediately terminated." But as their demonstrations bring them closer and closer, Hye-ju finds herself growing confused by Jung-woo's advances. Is this just a demonstration — or something real? A romance more dramatic than any novel is about to begin.
