Screenwriter just don't know how to do a good story, wasting a good premise with characters that are pure stupid, doing the worse decisions only to make the story longer. Childish jokes, adults that act as teenagers, specially Sol, that have a 30 years old mind in high-school, but act as a teenager. The only good thing in this drama is the OST, that is really catchy. If you're an adult with adult mind, run away from this drama.
