Similarities
-Both stories center around a family who lives in the middle of nowhere.
-Each family is morally questionable in their ways of earning money and keeping their business running.
-Both stories are dark comedies that center around a certain tragedy.
Differences
-In The Odd Family, the family owns a gas station and in The Quiet Family, the family owns an inn.
-In the Odd Family, the family finds a zombie with the weird ability to restore youth to the local elderly population by biting them and the family uses the zombie to make a ton of money. In The Quiet Family, people are dieing in suspicious ways at the inn and the family is continuously hiding the bodies throughout the property in order to not get arrested.
-There is no zombie outbreak and romantic plot in the Quiet Family.
If you like the Odd Family, then you would probably enjoy the Quiet Family!!

Similarities:
-The female leads are trying to deal with nasty gossip spread about them.
-Both male leads get into a relationship in order to protect the female leads from the rumors.. (Also how they eventually fall for the female leads)
-Both male and female leads technically meet at the airport.
-Both are centered around celebrities.
-Both are comedies.
Differences:
-In Her Private Life, the female lead is an obsessive fan of a local celebrity and is desperately trying to keep life her fan girl life private in order to keep her job. In Fluttering Warning, the main female lead is the celebrity trying to keep away from scandal in order to keep her job.
-In Fluttering Warning, the male lead gets into the relationship to avoid an arrange marriage and in Her Private Life the male lead gets into a relationship out of a misunderstanding.
Out of the two, just stick to Her Private Life but if the plot for Fluttering Warning sounds interesting, give it a shot!!

The stories are vastly different but I couldn't help but notice similarities between both dramas.
Similarities:
-The main female leads look and dress alike.
-The female leads are curious about the world but also shy (Heart to Heart's character has an actual social phobia and is WAY worse)
-The female leads knit and have a cleaning obsession.
-The romance between the male and female lead is VERY unusual and the people around them are always trying to break things off. (For the sake of the female lead)
Differences:
- Plot: Heart to Heart centers around a woman who has severe social phobia and slowly develops a relationship with her psychiatrist. Mary Stayed Out All Night is about a girl who's desperately trying to get out of an arrange marriage and gets into a fake marriage with a stranger she hits with her car...
- Romance:The psychiatrist falls and chases after the female lead first in Heart to Heart but Mary Stayed Out All Night is the other way around.
-Heart To Heart centers around the psychiatrist's job and the people they meet along the way whereas Mary Stayed Out All Night is focused on music and whether the female lead will escape the arrange marriage or not.
Both shows have a lot of charm to them and is great for a rainy day!!

Similarities:
-The female leads are played by the same actress in both 3 Nen a Gumi and Mask Ward
-Both stories are centered around a hostage situation gone wrong.
-Both stories have a theme of revenge and justice.
-Both deal with controversial topics
Differences:
-3 Nen a Gumi takes place in a classroom, and Mask Ward takes place in a mental institution/nursing home.
- 3 Nen a Gumi is about the suicide of a classmate meanwhile Mask Ward deals with corruption inside the institution.
- 3 Nen A Gumi deals with the corruption in society whereas Mask Ward deals with political and medical corruption.
I recommend both the drama and film if you enjoy a good mystery and psychological thriller.
