She writes filth by hand, in a notebook, in the year of our lord, and of course the step-brother finds it. The blackmail-into-assistant pivot is absurd but the show plays it for comedy rather than menace, which is the right call. Both leads are having a great time and it's contagious.
Episode 1 might make you go "what IS this lunatic" and bail. He's my favorite short-drama actor and even I hesitated. Please stay with it!! The acting is unreal, the way his eyes go, the way he smiles, each one gets me >_<
