There are a lot thinks I don´t like...
-When the OTP comes together too fast
-Clingy/Airheaded/Dumb/Stupid/Weak Female Lead (Something like Playful Kiss)
-Too much sensual tension (I´m happy if they kiss. I don´t need sex scenes or a lot of kissing scenes. Actually I really dislike those kind of dramas)
-A bad ending (Not a sad ending! I mean a generally bad ending)
-Too many cheesy and corny scenes
-Time jumps that are unnecessary
-Something with Amnesia or Gender Bender if it´s not good solved, unnecessary or annoying
-Second Leads or Love Triangles (I don´t hate it! I just find myself to avoid these kind of dramas because it´s so sad to watch the second lead...)
-Female leads that wants to do something but end up not doing it! (Like.. Girl, you don´t want to be hurt again than don´t fall for the next best person you see -.-)
-Dramas that are too long. 16 episodes+ are not always necessary!
-Characters and situations I don´t understand or I can´t relate to
