There is a lot of wasted potential in the 2019 tvN series Her Private Life (그녀의 사생활). A quirky, refreshing premise and a solid cast get shortchanged by a paint-by-the-numbers romcom plot that doesn’t seem to know where it wants to go or what it really wants to do. It’s a fluffy series that lacks the depth that could have elevated it to something more, even as the foundation was well-established in the beginning.
