Black Dog can be considered like "the daily lives of teachers", while Live was the daily lives of cops. both are taking the realistic approach to these commonly seen jobs in dramas.

Both main characters are new at their job and they are struggling with it, also both 2nd lead characters are like mentors

Black Dog similar to My Mister because they both have cold, slow and calming vibes. I also found the female characters kinda similar

REKNOW is the xing for you that we deserve~ both shows are like a documentation of the EXO members an individuality.

reknow is the "xing for you" sm tried to hide. but not on yixing's watch, he took 2 staff members and 2 cameras and did his own show.

both Love with Flaws and Yamato Nadeshiko Shichi Henge have that basic "female lead hates beautiful people" kind of a story ;)

both kinda talk about the same subject. the FL from HSH lies to her fiance and mother in law about her families house and pretends to live in an upscale apartment that's really owned by her friend.

every time I try to describe Haru, I keep going back to this point. Haru was really similar to Nam Sin 3. in some ways both were like new born babies? both had no real past, and in some ways that led to them being "characterless" in a way that everything felt new and weird to them.

Ma Dong Seok acts in both movies as the "bad" guy that is used to catch a "worse" guy? and both movies have the same concept of cop + criminal, against the more dangerous criminals

it's kinda funny that both Ma Dong Seok and Kim Mu Yeol acted in the bad guys series, but not in the same one.. KMY acted in the 2nd season while MDS acts in the 1st and movie vr.
basically the stories are the same, the cop/prosecutor work with the "bad" gangster guy to get a more "evil" enemy..

well Dramaworld is about a fangirl who ends up in her favorite drama, but the main lead there finds out that he's not a "real" person, just like the fl in Extraordinary You..

recommendations are not just about similarities, so I'll just say (beside be melodramatic) TTON is the drama that got me out of my HDL slump~
