Junichi (2019)

Both dramas depicted women at a crossroad in their lives or feeling lost in their daily existence. A mysterious young man entered their lives and offered them understanding and intimacy. His brief companionship encouraged the women to face whatever difficulties they might have.

A beautiful guy enters the lives of women and changes it. While Mother and Daughters is a more light and heart-felt portrayal, Junichi is a more mature version of that.

These two are similar in that a guy comes to a troubled woman and changes her life possibly for the better. Junichi is with multiple women while in The Lady Improper it's only one couple.

Junichi is a man who is unknown, he travels around and wherever he goes he happens to meet a girl and makes her happy intimately and makes her realise what is wrong with her life in some way and shows her, without words, how to be happier.
In RDWCS the story concentrates on the lives of five people who work together. As the story goes on they all discover what they are doing wrong in their lives and some even find unexpected love.

!!mature content!!

I would say Junichi is more of a Psychological drama, whereas RDWCS is a Comedy.
