The series touches upon depression and other mental health issues which are still too often ignored, dismissed or brushed under the carpet. Dealing with this weighty topic needs a light touch, and the series has done that quite nicely with a balance of seriousness and humour. At times the dialogues and scenes are comical, and at other times serious or painful. I see this as a good way to approach these difficult topics in a way that doesn't end up making the series too heavy, serious and hard to watch.

The kid brother Ba-Da was cast as being quite irritating and excessively immature for his age, but it did not distract too much from the buildup of the main plots and the interactions between the main characters. I really liked the sweet interactions between the secondary ML/FL, that was heartwarming specially towards the last few episodes. The development of the relationship between Jeongwoo and Haneul was a pleasure to watch, though I would have loved to see deeper conversations and more depth and dimension to this relationship.

Yes, some mysteries and sub-plots were resolved early on without dragging them for the whole 16 episodes, but the series doesn't hinge entirely on those plots, rather, it's about the underlying issue of mental health during the good and bad times that pervades all the episodes. PHS's expressions and comedic timing were perfect. On the whole, I enjoyed the show and liked how it was wrapped up neatly with a positive message.
