NOT A MASTERPIECE:
I don't understand why people are giving this such a high rating and praising it like it's the best of all time, but no, please don't listen to them as they have poor standards for a series, and WHY?
Because
The acting was very terrible , but the main characters barely have any emotion and are simply bland, the character development was poor, and all the minor characters were just plain dumb.
The plot was decent, although they could have gone deeper with it and just be accurate to the webtoon. The entire series will have left you with a plethora of questions.
My final verdict is that this adaptation was floppy and just average, I would give it a 1 star at best if they just used the right music for its emotional scenes. And for those that only wants to be average and watch average, then I suggest you watch this.
