Our male and female lead have known each other from high school. He was accused of guilty in an incident, but we don’t know the truth yet. Later in life, they reconnected when he decided to go back to school where she's works as a part-time teacher...

First thing I have to say: this premise is jarring. I have never seen adults mixed in with high schoolers in one class, but it doesn’t really matter. What I’m so intrigued by first place is the over-the-top extra-ness of the show. Every aspect of this show is operating at >100% level. The music is just so dramatic, as well as the acting and the filmmaking. Normally I dislike this tone, but here they all works together, so kudos to that. Yoo Seung Ho’s acting pulls it off. You can tell that he’s just having so much fun with his role, and his enjoyment seeps off of the screen.

Now, for the storytelling, I think they nailed the present and past storylines switching really well. Like you might have questions during the present time, and then you’ll see it unfold in the past, and then it ping-pongs back and forth. The writers know how to pique your interest. The questions keep you engaged because you'll have one answered, and then you're given another one.

My con comes a bit later when something happen to the couple, and the female lead response to it really rubbed me the wrong way. Since then I feel a trust issue that relationship wasn't genuine and so, it felt almost like a chore to finish the show. The ending was satisfying; it tied all the loose ends.
