It seems like it's been marketed as a madcap comedy, and it's funny enough, but that's not what made me rate it so highly.

Two supporting characters are unique, and i thoroughly enjoyed their development. The emotional maturation of the characters comprehensively won me over, it was a joy to see the progress play out over such a relatively short season. Big thumbs up to the ML. He had a lot of range to cover and was as funny as he was charming—some great relationship advice for anyone stuck in their own head.

On my short list of recommendations to people new to kdramas.
