Definitely a slow moving drama, the plot didn't really reveal itself till about halfway through the drama. The first half of this drama is mostly build up- the characters participating in the love triangle are revealed and early character traits are shown to leave room for development throughout the other half of the episodes. The fact that's it a slow drama is not a bad thing! I personally don't mind slow dramas as I can take my time to watch them however, I did think about dropping this.
The reason being how slow it was, but I decided to give it another try and make my decision through the next episode. From there I decided that I would keep watching it through to the end as I really wanted to know how the love triangle would play out. In the end I'm happy I watched this but I don't see myself watching this again, it's kind of a one time watch drama.
