The lamest korean series. Totally unconvincing acting, the protagonist always having come out of the hairdresser's, her make up always perfect, never even smiles once, always angry, both actress's wardrobe could easily be used to open up a store, lousy acting. The secondary actress even worse. Smiles when she shouldn' t, taking weird facial expressions, more so to show her dental work. Lousiest acting. The playwright totally unconvincing thinking that this poor girl who works as a cashier at a sm can learn the business world in a month and mess with korean companies that have been around for 40 years. Music constantly playing in the backround. An absolute piece of garbage. The worst s corean series I've seen. A low quality soap opera. The only thing that's worth is the older guys's acting.
