The show overall was very enjoyable to watch. The actors did a great job with the material they were given. I have just two criticism and it's at times a bit illogical plot structure and the OST.
Some of the "conflicts" seemed exaggerated to the point of not making sense whatsoever. And I totally understand that a show like that will present not very realistic scenarios and it will make some things much bigger than they should. I went into this show with that expectation. It was still waaay too much at times.
There were some plot holes and at the end some of the unfinished story had me asking questions.
Some of the dialogue felt a bit stiff and unnatural, but Idk if it's the translation error or not.
All of that I blame on the script, cause the actors were splendid. I really liked the main characters chemistry and tension they managed to create. It was really nice.
My other issue is the soundtrack. There were moments where the sound effects or the music really didn't fit. And again, I'm used to shows using weird sound effects for the comedic value. This wasn't it. Usually I don't really notice the soundtrack, unless the songs are very good. This time I noticed the soundtrack, cause it wasn't that good. It's a shame really.
