The drama lacked the Korean flavor in its adaptation from the original Japanese one. Usually when the source is Japanese, the adaptation will take the core idea and add its Korean spin but not in this one. This feels like it was fully produced by Japan but with Korean cast. From writing to dialogue, characters and editing, even the teaser at the very last scene. Speaking of the cast, this is Kim So Eun worst performance, I've seen from her other roles and she's usually better than this, I don't why she's like that here.
