One day i was in pain(flu) in the bed n so bored  of every thing when by coincidence i saw High Kick 3 and the rest is history 

Who would ve known that long family dramas are crazy!!?

So ive been  watching this genre recently

But ive found out its hard to watch them because there is no Eng Subs 

Please recommend me some that are

-from 2010 till now

-20-60 minutes

-Korean only

-20 -200 episodes

-no terminal diseases

-no break ups

-many generations meaning( grannies ,parents,teens,kids ,and youth

-good looking actors

-no serious plots

Only one that I can remember being pure fluff.

I second Family, it fits your description perfectly.

I only watched half of these two so I can't guarantee that characters won't be falling sick in the second half but it would be very strange if they did:

Life is Beautiful

All My Love

And of course all of the High Kick series though the first ones are older than 2010. :D
