Recommendations

Both movies about gay relationships in Korea with Korean men. Currently not all Korean BL movies are linked as recommendations so I think people will want to look at table manners too which is why I recommend checking it out.

Both centered around Korean men and LGBT relationships. Both are fairly short movies with cute interactions between the characters.

Same actress, the plot is similar as she becomes an assistant and develops relationship with the male lead. They're both are based on a cute and funny romance storyline and is set during their youth.

Same actress, its based on a cute and funny romance relationship and the male lead both are charismatic. It is set during their youth and that develops into adulthood, with several twisting plot . Truly a must-watch. Li Hong Yi needs more drama of this character.

Similar in a way because both are in the medical field...and both "met" again after a long period of time...somewhat similar...but the only difference is that the FL in Koi wa Tsuzuku...is the one in love with the ML; while in Doctors, its the other way around...

Both taiwanese drama about time travel to the past about 20 years. Both very touching and focused on relationship between 2 people from different timelines.

Both scenarios are almost the same with little difference. Moms trying to bring back dad and try to settle her child after her death

Lee Jongsuk acted as male lead in both dramas and they do have the same fantasy and unreal stuffs.

It is because W and WYWS are both written by Park Hyeryeon. So if you find interest in one drama, maybe you will like the other.

Both has multiple couples and show development of all them. Enjoyable easy going comedy with romance.

both dramas are gaokao related
however, a ilttle reunion also focuses more on the daily lives of the families and the struggles they go through
both dramas are very realistic

Both movies depict story of a disaster and struggling of people to be survived.
The Exit is mostly focused on the escape plan of a couple (not really couple) but Ashfall is more team oriented

Both are action thrillers that feature a begrudging partnership between a South Korean cop and a North Korean officer. The two gradually become a part of each other's lives in order to fulfill mutual goals while slowly building up a fragile trust, oftentimes to comedic effect.

Both are adaptations from a manga that contained elements of time-travel. And amazingly enough, both also involved an incident set in Hokkaido while the protagonist was currently based in Tokyo. Also, both involved the protagonist being from a future with bad outcome ending up returning to the past to try to prevent incidents happening in order to change the past and future.

There is somewhat of a spoiler in this review for both dramas.
The only similarity is the twin aspect. I find the twins in both Arthdal Chronicles and Duel to be similar.

In Duel Sunghoon and Sungjoon are mere clones however, the two are very different. Saya in AC reminds me of Sunghoon so much. The two are both very stylish and the more well-kept compared to their twin-counterparts. Both of them are very eerie and are super smart. Both Sunghoon and Saya are evil but as a fan you'll find it very very hard to hate the both of them. Both twins are lonely and were mistreated as children.

Now we get to Sungjoon, he reminds me of AC's Eunseom (aka Saya's twin) because they both have a sense of doing what's best instead of their twin-counterparts. These two aren't entirely similar as Eunseom at the beginning and sometimes near the end is very naive this is due to how he grew up. Sungjoon too is naive but this is due to his memory not being fully there. Other than this you still find yourself routing for this twin as well.
