both Birthcare Center and Spring Turns to Spring are female centered, both have Uhm Ji Won and both are hilarious

the comedy sense is kinda similar between Birthcare Center and Pegasus Market though, Birthcare Center is slightly less crazy xD

in angry mom (I personally) shipped the fl with someone her kid's age and though nothing happened, here in 18 again they are bond to use that tension so it's not really that different from angry mom but here the guy her kids' age is actually her same aged husband?

also both show parents go back to school and blend in with their kids' lives and try to help them

both use high quality set production and interior decorating from scratch. and both also make up scripts to utilize those sets though in TGE they need to escape and in SS they need to find that one "set"

both shows are about finding the "fake" among the real things. in ICSYV it's about real singers and tone deafs and in SS it's about a real restaurant or office and the sets the writers made.

also both shows have really creative writers

the stories start similar, both are wrongfully accused of killing their spouse and both don't remember it (or LAL is not telling the full story for now) and both are parents that get separated from their kids + "rich" people are out to get them

both have a somewhat similar story line, both are melodramas about secrets and deceives and both are "wrongfully" accused/give birth in prison

both Another Way and It's Okay to Not Be Okay had hurt and traumatized leads that in some way relied on each other though in Another Way the mains barely interacted.
also both have Seo Ye Ji

the concept from ep10-11 in The Great Escape: Season 3 is the same era as Mr. Sunshine, 1920s-1940s ie the japanese colonial period

both are done by the same screenwriter, and both are scifi fantasies. one is about time traveling and the other is about dual universes ;D

if anyone wants to see Seo Ye Ji in a more "normal" yet still strong, independent and fashionable role after It's Okay to Not Be Okay then they should try Quantum Physics

both Birthcare Centre and Avengers Social Club are female centered and "black" comedies, ie my type of story
