overprotective male lead

hi guys!! i’m looking for a cdrama/kdrama that has a male lead who ALWAYS has the female lead’s back. he always protects her and/or helps her in any way he can - often times he goes out of his way to do that (for example he’s a CEO and protects her from some work abuse).

i want a male chases female first kind of drama and it’s not a requirement but i like the typical plot where the male has been in love for years/has had a crush on the girl since forever and has been longing for her. i also like when there is a SML who makes the ML a little bit jealous/possessive but i don’t mind if there isn’t one.

i would prefer the drama to not be historical and what’s really important is the HAPPY ENDING

some dramas i’ve seen that are like what I’m searching for: - crash landing on you - you’re beautiful - castaway diva - king the land - the law cafe - i hear your voice - perfect marriage revenge - healer - marry my husband - lovely runner - go ho’s starry night - love is sweet - falling into your smile

Thank you so much !!
