Recommandations

Both are about fortuity, chance meetings and other little things joining the main characters.

These series have a plot, a filming approach and accents of various kinds. However, a sorely specific situation is the basis of dramas. There are a prisoner's family and a victim's family. One day these families’ members meet each other.

Both are about people who show love towards wine and women.

Both films are about two strangers who meet by chance while abroad and fall in love. Late Autumn is more dramatic though.

Both kids come into the new environment, they don’t want to follow rules and to be like everyone else.

Almost the same storyline. Time travel, princes..etc but moon lovers seems to have a open ending. This one is more happy ending comparing to moon lovers but moon lover got better ost.

Both dramas have similar plot where the romantic relationship between a boss and employee become the center focus while also we are able to see two other couples forming.
Both dramas fall in the genre of romance and comedy.

Themes of depression and suicide, overly protective parents, situation where a teen feels out of control.

Both of these jdramas feature older woman/younger man romances, and both have male leads that are dancers. The progression of the romance is fairly similar, but Second Love is a lot faster with intimate scenes.

Absolutely amazing film Double Mints will forever be ranked high on my list.
It has flawed characters that are trying to make sense of the darkness in their lives.

Both will break your heart but you can't stop watching.
Night Flight is just as brutal as Effect but it's a bit more nuanced where Effect is more guilty pleasure.

Haechi is about how twisted the political condition in Joseon Dynasty. On the other side, Six Flying Dragons consist of 50 episodes, from the journey how Goryeo Dynasty become Joseon till all the civil war that happen. Both are heavy historical political drama and have good actors.

Each one is a supernatural movie that is targeted towards a family audience. They have hints of horror in them and they both have interspecies romance. They're really funny too.

In both dramas the male lead is connected to the death of the fiance of the female lead. In FFI, the male lead has the dead fiance's heart, while in CFY, the male lead causes the death of the FL's fiance. FFI has more comedic scenes.

In both, the protagonists' families have been in an accident, and both have a fear of water. They are lonely girls who can hardly bear the rainy season.
