The plot is identical. Almost too similar, to the point that Umi no Hajimari looks like a total copy from My Girl. Both main characters are young males that were dumped by their girlfriends and years later find out that the ex-girlfriend had passed away. In the funeral both of them find out that the ex-girlfriend had a secret child, a young girl, and that they were actually the father. The details on the stories diverge, but overall they look identical to me. ^^"

A slightly similar premise with a work related romance. There is an age gap between the male and female leads, where both women are the older ones. Also, there is a fair amount of skinship in the two dramas.

Both dramas are focused on the fact that the male leader has became a ghost and can only be seen by the female leader.

Both dramas start with the main character waking up from a coma with amnesia.
The two main leads can't remember who they were, their family members or where they lived.
There is a mystery behind both characters, and we know as much as the character does, so the story will reveal itself as the episodes go by.

Both dramas are about Konkatsu, the japanese marriage hunt. The two of them show the struggle of women in their late 20s/ early 30s trying to find a marriage partner. They are both fun and easy to watch dramas.

They are both fun to watch, and are a great mix between action and comedy.

Both are family dramas about a patient that needs medical care at home.

There is a girl as the main character of both of them.
The characters are unique and charismatic.
