Dramas/movies like Sassy go go/cheer up

So i'm kinda obssessed with this new drama called Cheer up! and I think the plot is so fresh and cute,plus I love high school dramas...:D 

Anyways if you could find me more dramas like that,which include a hate/love relationship between the leads and something cute but can get to its dark point as well xD

The Queen's Classroom is my favorite kids drama

Angry Mom is similar to Cheer Up in cuteness/darkness 

And of course Dream High (Although I'm preferring Cheer Up)
