Drama recommendation needed

Based on what I liked so far
Secret Garden
Rooftop Prince
Shut Up 꽃 Boy Band
Dream High
Lie To Me

Pls no gender bender 또는 historical stuffs.
I really want a drama which can keep me interested and the fillers, boring parts are not too much.
Just recommend a few( not a long confusing list), giving reasons why 당신 liked it
Thanks in advance
