Like many others, I started watching because there were some actors that I really enjoy watching in other series (Gun, Off, Singto and Krist). Just like I was expecting, the acting was VERY good and the emotions were well-portrayed in every scene.
What I felt was lacking spark was the plot itself. There isn't anything big going on for most of the series and even the little tropes sprinkled in don't do much to make it more lively. For the most part I kept watching for the main actors, but after a while I struggled to finish because of how monotonous the story was. I'm usually a big fan of fluffy stories; I manage to enjoy them even when they are predictable for the simple fact that they bring me comfort. This time around it simply didn't happen, and while there were some moments that caught my interest every now and then, by the end I was forcing myself to finish.
I believe it's a pity, because the potential for an interesting plot was there (maybe by making the characters interact more with each other, beyond their respective phobias? Or by creating good foundations for the "climax" of the series, which fell on us completely out of the blue and only managed to confuse me instead of making the show more interesting?). It can be a good series for someone who is looking for something light to watch, but that's it.
