Can't recommend this enough. It truly is one of the most underrated dramas of 2018-19.
That being said, I am so glad Lee Yi-Kyung got to experiment with such a remarkable character exhibiting his versatility, given his flair in comedy has already been established. The story is very engaging and binds everything with so much finesse. Every scene and dialogue is important leading up to the conclusion. Top-class acting as expected from the ensemble as they have already made their mark in the industry.
Kim Sun-a has such a character arc and portrayed her turmoil and frustration with such ease. Her eyes do speak a lot more than what is hidden. The final episodes showcase her explosive acting skills when everything is exposed in the end.
The drama is so well written, much kudos to the writing team for shedding light on a grim and less-explored reality of children.
