Sweet Hearts and Sharp Minds- Modern Dramas (HE)

There's some of that but it's the SML protecting and loving the FL.

ML and SML are protecting FL in their own way. ML because he knows FL's secret.

Bad boy ML protects the sweet/innocent FL. Definitely what you're looking for.

Bad boy ML... at first dislikes FL and picks on her, later he likes her and ends up protecting her, etc.. (this one is Chinese)  

Not quite bad boy, he's more on the cold/cool side but definitely has the bad boy looks and exterior.

Kind offff?? Definitely on the cold side.  

This one fits for the 2ML...

This one also fits for the 2ML... but I guess the ML can have some cold vibes to him..

Fits  description perfectly... the FL isn't really super sweet and innocent

Another kind of bad boy exterior. ML gets into fights, etc. But has kind heart with a lot of emotional baggage.  

More of a bad boy ML, definitely has an interest in the FL.

Not the main couple. But more of a side ish couple..  (FLs friend Fang Fang and the love interest Lin Yi Yang... he's the literal definition of bad boy protects and falls for sweet/innocent girl.)

 (bad boy later ex-juvenile ML  loves helping people, protecting both FLs most of the time, at first FL1 is innocent but because of poverty changed. FL2 is somehow sweet but not innocent)

(At first FL1 is sweet and innocent but adapted to situation. Badass ML1 is always ready to help in secret. For FL1 there's little to no romance. FL2 is straightforward and naive, also adapted. ML2 is not badass but he helps FL2 as much as he can)

(ML2 acts like a bad boy but actually caring, ML1 (ML2 and FL1's son) is brave and protective. FL1 is sweet and innocent)
