You may find my review headline weird of sort. This isn't a drama about school of any type or grade. However, for me the experience I got from watching this drama was the same I got when I watched School Days the anime.
In fact, I stopped watching dramas for about a month after I finished this one. I skipped a lot toward the end as well and it still get on my nerves to this day. I came to this after I watched the Flower of Evil. Both of them has the same female lead which I liked after watching the Good Doctor. The actress there was so bright and gave me a good and warmth vibe. In Flower of Evil she showed lost of those great feeling. Even in this drama, I don't blame her or her character. I hated the love triangle and how the male lead kept hanging on the other witch. It was hard for me to keep watching while those two kept hanging out. That witch was the worst character I ever saw till this day, and that guy was so annoying to the extent where I skipped his other dramas besides Vincenzo.
I completed this drama with a broken heart not for what happened at end but for the huge amount of corruption of morals I experienced while watching it. It's indeed School Days of Korean Dramas.
