I'll keep this as brief as the episodes themselves; none of this is based on investment in the plot but simply intense acting and facial expressions sold magnificently by IU. She is Korea's standout actress and standout singer, and we can see why. She delivers a range of emotions sometimes through the power of her voice and sometimes through her body language. Even when the plot itself feels incidental, we are gripped by her persuasive acting which reels you in and makes you feel like these stories are bigger than what they are.
