There are more similarities...but to find that you will have to watch!

Both are centered around a female lead who has to give up her first love in favor of a political marriage. The dramas are relatively heavy on the politics, but are truly driven by their romances. Despite having more focus on the drama and court scheming, both also have their fair share of action and battles. Empress Ki has more interesting characters, while the The Rebel Princess has really gorgeous production. Disclaimer: I ended up dropping The Rebel Princess, so can't vouch for the second half.

Similar feeling of a love story through different times. Both stories show scenes out of context and slowly fill in the blanks. Until We Meet Again deals with reincarnation while Some Day or One Day deals with time travel.

Both are BL dramas. In Oxygen Gui makes Solo warm milk every night so he can sleep. In Mr. Heart Sang Ha delivers a milk carton to Jin Won everyday so he can become a better runner. Both Gui/Sang Ha help Solo/Ji Won find motivation to purse their passion again Singing/Running.

They are basically about a teacher that is in charge of a class that has no discipline. the teacher is able to connect and help out in the students lives and motivate them to study and think of their future.
a plus both teachers are really good fighters and end up getting into fights, which gives it some interesting content to follow.

Both of the movies are about a geeky IT employee who likes their pretty co-worker. They both don't have the courage to confess to the woman, so they admire her from afar. On a trip, both women lose their memory, and the geeky IT male lead has the chance to pretend to be the girl's boyfriend for the time being.

Both dramas are set in historical era with a romance-comedy genre about how the female or male lead are pets

In both dramas the couple meet and fall in love after meeting again in another time period. Wonderful story, production, acting, and osts.

These are both really sweet chinese movies/dramas that focus on two students from the same hometown falling for each other and attending the same college.

Well written warm and sincere story.
Well-written characters.
Slice of life.
Longtime friendship.
Eating together.

Another drama partially set in the past, tha has you guessing what happened to the characters and what led them to their present life.
Reply 1997 and My First Love Is Secret Love are both heavy on nostalgia, abeit they start 11 years apart.

Also set in 2008, Go, Back Diary is about high schoolers experiencing their first love. Webdrama is short but has a lot of developements packed in just 4 episodes. We are also told what happened to the characters in present time.

Similar concept of promoting Korean cuisine abroad by setting up a temporary restaurant/pocha (in France for Olive Pocha and in Spain for Youn's Kitchen) where Korean celebrities do the cooking and serving.
