The story is not bad, but it doesn’t make the relationship between the leads of ok. Having a crush in your teacher can be normal but actually writing a story of confesing those feelings and acting on them is crazy. In real life the actors have a 15 years difference and for the first few episode I was so uncomfortable watching hoping that the female lead would not become a freaking pedophile by becoming interested in the male lead in his school years and that feeling accompanied me in the rest of the drama, I personally could not get attached to their relationship at all, thinking about . The good point is the acting, the redemption of some characters as well as the revenge plot.
