Recommendations

Both dramas have a firefighter male lead and a doctor female lead (that works in the emergency department)
There's also a romance between them

My Fireworks on Earth is also a firefighter drama with a firefighter male lead.
There's romance in both shows

One takes place in the 70s, the other takes place in the 80s. Both are coming-of-age dramas about pursuing dreams and ambitions, with economic reform as backdrop. Both have Li Qin as the FL.

Main characters are separated and find each other again after a long time. We follow their story in the present while learning more about their past and what fate separated them and then brought them together again.

Similarities
-Both films tackle regret set in the female lead's youth.
-Both films are incredibly nostalgic and heart-warming
-Darren Wang is in both films
-The younger female leads are very naive and can be a bit unpredictable.
-Great cinematography
Differences
-Suddenly Seventeen is way more of a fantasy than Our Times.
-The main female lead in Suddenly Seventeen mentally turns back into her seventeen-year old self whenever eating a chocolate whereas the main female lead is looking back at the regrets of her youth.
- The relationship between the male and female lead is WAY better in Our Times than in Suddenly Seventeen. Not sure if it was the acting or plot, but the main male lead appeared to care less for the female lead throughout the film.
Both films are very charming and still very enjoyable. Worth a watch!!

Both are historical fantasy movies in which the ML strays into the mysterious world of the afterlife and falls in love with the non-human FL.

Other than the zombies, these two movies have a lot of similarities. The overall themes are the same, there's infection within a plane (eerily similar to the train), and the main character is a divorced father who is taking care of his daughter. Both movies are brilliant, and are filled with suspense.

Similarities-
-The main leads must interact with the past in order to change the future.
-Both stories deal with a serial murder case that started in the 1980's and is still occurring in the present.
-unpredictable story line with several plot-twists.
-A love interest is murdered spiraling the main character into solving the unsolved case.
-The story starts with both characters getting a severe physical injury.
-Nostalgia atmosphere/aesthetic
Differences
-Life on Mars has one male lead experiencing a time traveling phenomenon, whereas, in Time Renegades there is two people.
-Life on Mars is much more of a buddy cop police drama whereas Time Renegades is a psychological fantasy based around the crimes surrounding the love interests.
-There is more of a focus of romance in Time Renegades than Life on Mars.
-Life on Mars is more comedic than Time Renegades.
Honestly, both stories are underrated and great picks for time-loop dramas. Definitely check it out!!

Similarities
-Both female leads are played by the same actress
-Both stories are set in two different time periods that intermix with one another
-Both are action/ thrillers
-Melancholic/nostalgic atmosphere
-Both the drama and film have a great soundtrack
Differences
-Chicago Typewriter is set in the 1930's and is a spy drama whereas Time Renegades is set in the 1980's and is about a serial murder case.
-The female lead is stronger in Chicago Typewriter whereas a damsel in distress/victim in Time Renegades
-Chicago Typewriter is more comedic than Time Renegades
Both the KDrama and film are very entertaining and a great double-feature!!

amazing chemistry between the main leads. Fantasy+ historical (both are costume dramas), they both have strong female leads. There is power struggle in both dramas. In both dramas the main couple is willing to sacrifice themselves for each other. In both dramas a close family member of the fl is killed and she wants revenge. In both darmas the ml is the son of a king. In both dramas the romance is developing not that slowly but not that quickly as well.

Both involve two men where one seems very suspicious and the other is convinced he is a murderer while you as a viewer is confused about whether or not he can be trusted. The dynamic is just similar. TSHLYE is romance-focused, though.

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!!

From the synopsis it looked like both of them have the same underlying plot of a single mother who raised her kids abroad and came back home and meet the ml.
