Series with a female obsessed with a guy?

I've noticed this is a genre that isn't very common. I've seen some gripping tv series of males obssessed with females so I wondered about the opposite.

I know about Gumiho, It's ok not to be okay, Itaewon Class, Love from the star, legend of the deep blue sea, hotel del luna.

But are there others? Are there also dramas where it's very intense? Ideally non-anime. 

Thanks

very good examples are here, I would add:

Hello Mr. Right  she is really obsessed with her teacher, though it's taboo still sweet and cute and good watch, + she is soooo lovely 

Nine: Nine Times Time Travel 

Cruel City 

Memories of the Alhambra 

Girls' Generation 1979 

there are more, but I think better fits are here ))
