@Lopkiu: Everyone talks about this Drama because it is so dramatic in terms of life changing (In some cases){For me=P} but it is probably the best drama to begin with for any viewer.
Yes there is a Movie version of it, but I, myself have not seen it so I can not voice my opinion to compare.
But yeah this drama is definitely a must watch as it shows just how some diseases can really mess up ones life but with the right attitude you can try to make the best of what you have.
