Rich girl navigating the country side life.
Sweet hardworking ml.
ML has a very obsessive fangirl stuck to his side.

the 2 stories are about a married person (the wife in marry my husband and the husband in familiar wife) who is unhappy in the marriage. the main lead then mysteriously travels to the past and decide to change his life and makes different choices.
in marry my husband the main lead died before she comes back to the past and gets rid of her husband.
in familiar wife the main lead just accidentally traveled to the past and then decided to get rid of his wife.
the mood of the stories are very alike, but the 2 stories end very differently. familiar wife is very promising in the beginning, but I found it disappointing in the end. but it's still a very unique scenario.
