-They both have a CReEPILY similar vibe, despite the plot being totally different
-They both take place in a very new, modern, brightly colored and unfairly spacious boarding school (although, Kim Bok Joo's is a college (so, duh, they live there) and To the Beautiful You's is a boarding high school)
-The best friends are the best part (side only to the romance if you're more into that thing)
-Both revolve around the main characters' sports and a primary plot line is training or overcoming some (or several) sport obstacle(s)
-They both feature rhythmic gymnastics as a sort of side plot (and the participants are always the mean girl)
-Both have a strikingly similar ratio of humor to drama; the humor being of the same type/style, and the drama relating to the mother of the male lead
-For some reason the school's doctor is a friend/somewhat needed side character that falls in love with one of the two lead's siblings
-Even the originally bad characters become lovable
AM I THE ONLY ONE WHO SEES THIS??

-Both are crime dramas
-Very similar vibe
-Both follow the main character (who is a young rookie detective, still holding onto his dark past involving the police versus criminal-minds-esc bad guys, and because of this he often lets his emotions control his actions and judgement) and the other characters on his detective team while they work to solve many major crimes and cases (roughly 6-8 throughout the season) that lead up to solving a major case
-(Signal works with cold cases and Hidden Identity just works with cases revolving around a mysterious person named "the Ghost")
-Both feature 1 badass female on the team who's past is also dark, mysterious, slowly revealed throughout the series, and affects her judgement (although less than the past affects the main character)
-You fall in love with every single character on the team - no matter how small their roles
-The dramas do not shy away from tragedy, violence and heavy/dark plot twists
-There's always that "there's something else going on here" vibe
-THE PLOT TWISTS THO. ... yup. Imma just leave it like that.
-The acting is INCREDIBLE. You will cry. Multiple times, probably. It will hurt. But it is amazing
-Both make you wonder, "what kind of sick, twisted, brilliant, talented person could come up with/write this plot??"
-No romance... (technically)... Trust me, you don't need it.

-Overall very similar vibe
-Both are actually funny, like I-almost-peed-laugh-out-loud-cute-funny
-Guy is chick's boss
-Chick is a badass but gives off a natural vibe of something else (Strong Woman: chick is supa cutesy, Protect the Boss: chick is awkward and cringey but amazing)
-Workplace romance that started from experience with chick kickin' the crap outta some dudes that actually had nothing to do with the workplace and then it does cuz then she's hired and batta-bing batta-boom
-Love triangle-y
-Leading dude is kinda wimpy, but then wants to protect the chick, but then again he's kinda wimpy (he will have his strong moments tho)
-SUCHHH ROM AND SUCH COM (Protect the Boss gets a lot more serious toward the end, whereas even Strong Woman's most dramatic moments had a comedy vibe)
-Lots of powerful quotes
-DANNNNG that chick can speak for herself
-AANND she can hold her own. Yeah that's right male lead, I'm looking at you, that means she's just as fine without you or any man for that matter
-A good female friendship between main character and side character (Protect the Boss has multiple female friendships)
-A funny, awkward butler-y secretary of dude guy
-Guy falls (in love) first
