In Theory of Love, there is a pile of movie references, among them, Dear Dakanda. TOL's first episode name is because of this film.

On the other hand, both productions tell a story about secret unrequiment love for a close friend in a college ambient.

- Same director.
- One character from My Girl appeared in Dear Dakanda.

Both films talk about first love, how is to fall in love and friendship.

Republican era drama setting with Japanese x Chinese war as background. There is thin line to define who is your friend and who is the traitor.

Espionage drama with 1941 era setting background. The main lead go undercover as Japanese agent. The danger of playing between 2 parties is the main theme of this drama.

Both dramas the boy and girl do not like each other and have sit together
At first they don't like it but then they can't sit without each other wow CLAPS
Both dramas the boy and girl are pretty different from each other
And lastly both dramas the boy falls in love first

It has the same sweet and same vibe of 2gether, just a slice of life type of storyline, not too much drama, but with an ample amount of bed scenes.

-Both have the main leads with a physiological problem.
-Female Lead is a doctor.
- Rich Male lead.
........................................................................................................................................................................................................................................................

The female lead lives in the modern Republic of Korea, while the male lead lives somewhere more outdated and dangerous. Both have travelled between their 2 'worlds'. Especially at the end of both dramas, when they have to go their separate ways and the main lead has to return to where he is from.

Just like 2gether, Kiss Me Again also featured BL relationship in one of its main characters. Although both of the shows had the same Director (Champ), I think Kiss Me Again was done better compared to 2Gether.

We are presented with the fundamental question of whats right and whats wrong?
Also, I cant help but draw comparison from wei wuxian and zhao feng both extremely value the people around them they are pure yet the world is making them suffer.

I really couldn't bare this drama through to the end, however I know some people that did, so I recommend Angel's Last Mission to anyone that enjoys plots similar to this one.
Both dramas feature L as a main lead and personally I enjoyed the latter as there was a much stronger plot complimented by the comedic arrogant female lead :)

both dramas are similar in a way that the plot surrounds students being pushed to do extreme things in order to pursue a successful future.
however, sky castle focuses a lot on family reputation and how one failure in the family can drag everyone down altogether, leading to a lot of mind manipulation and emotional casualties.
definitely recommend watching sky castle if you enjoyed extracurricular!

Both have Multiple strong female leads & Sismances in focus.

Angel Destiny is a severly under-noticed drama with great writing.

Multiple strong female leads & Sismances.

Great writing in both, but Angel Destiny has even better writing.

Both have similar light, fluffy vibes. Both dramas have smart and good-looking male leads, and beautiful female leads (who are in a way independent). In both, the chemistry between the leads are cute and adorable, with sweet moments that will make you smile and "blush". They are definitely one my favourite dramas of all time.
