Terminal illness

While the acting will definitely feel very amateurish to some, if you can forget that bit and focus more on the content, you'll like this one. I highly recommend reading/buying the actual book as well.

Not terminal illness, but one of the main characters falls into a coma. The series revolves around finding out what exactly happened. It also explores the impact severe bullying can have.

This one was superb.

This series and many of the episodes, are kind of like stand alone short stories. The first episodes are there to establish the main and supporting actors you'll see towards the end of the drama.

One of the main characters has cancer, though it's a very small part of the series over all. It does bring up several cases which involves terminal illnesses though.

It's short, but not too bad.

This one was quite good. It did feel a bit draggy towards the end. 

While it certainly is a ficticious illness, the end result is death. It's a big aspect of the main male lead's character.

The main FLs all have terminal illnesses.

While it definitely feels dated and the terminal illness part is only during the latter part, it's still quite good.

I really liked this one. Great characters.

Not terminal illness, but rather a female lead who wakes up from a 17 year long coma. The reason for the coma was a bus accident and it focuses on her getting back into society after she wakes up. 

It's for the most part light and quite good.

FL finds out that she has cancer.
