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

Both are office dramas about bad bosses and hard working environments. While Feel Good To Die is a fantasy genre both are comedies

both Kkondae Intern and Search: WWW are office dramas and both main leads work for the rivaling company of their former work place

the 1st ep of Kkondae Intern had the same mistreatment/bullying by the senior in the workplace as To Each His Own
