The first part of the show was indeed crazy, I loved episode 2 the most, the fact that without loosing her humanity but taking vengeance upon this narcissistic CEO was so satisfying to watch and the crazy Krystal was beautifully mad. How they turn the clichés, how they finish them, how the relationship developed, the only and it's not nothing, but my only dissatisfaction from the first arc of the story were the instructors which were boring so I skipped and skipped a lot.
The second part of the story, how to tell you, was so conforting, healing, soothing, it was the less angsty thing I watched, problems were solved without much dramatic and tension and yes it wasn't waouh but sometimes I just need these kinds of dramas that don't break your heart into pieces.
How GoJin didn't understand why everybody wanted to harm him and took time to realise it and finally saw how bad he has been was realistic and him apologizing, it's just perfect, not a perfect drama had flaws, but when my number one comfort drama.
