A Perfect Couple of Episodes, Until it Suddenly Undergoes a Genre Change

So we start watching a Romantic Comedy Korean Drama, and we all know now that after episode 12ish that all the sudden the crap will hit the fan and no matter how funny the drama started out, it will suddenly be a melodrama (just think how Emergency Couple was supposed to be a RomCom, but the whole second half was complete melodrama... which was actually so much better than the comedy was).  I don't know if this is a case of the dramas being "Anthony'd" (King of Dramas reference) or if the basic plot has to do that to complete itself, but seriously.  When I start a RomCom, I'm looking for comedy and romance, not melodrama.  Not sad stuff.  Funny.  With kissing and couple cuteness.  Fluffiness.

I don't know what it is about Chinese/Taiwanese Dramas, but they seem to take the genre changing even more extreme than is typical for Korean Dramas. It's not even funny how all romantic comedies start out cute and funny and by the second half of the show they are suddenly melodramatic.  I've come to just accept that fact, but recently, there has been too many over the top genre changes for my taste.
