-always about bad rich boys that are tamed by good religious girls
(So repetitive man. Every single drama. The concept is good, but overused.)
-bad boy's mom and ex gf is a bitch
-ex gf and mom gang up to prevent bad boy from falling in love with good girl
-bad boy's dad is a pussy for not standing up for his son until last few episodes
-bad boy teases good girl and yadda yadda yadda until they fall in love
-good girl's bff gives good advice that is cheesy
-mandatory dramatic hospital scene at the same hospital
-mandatory wedding
-sappy love songs at "dramatic" scenes
-OPTIONAL: pregnancy (which means an additional hospital scene)

And my favorite:
-THEY'RE ALL BOOK ADAPTATIONS
(Not that I don't like book adaptions, but please, create something that's NOT a book adaptation for once?)

That's why I watch Chinese dramas. They're better.
