The ending gave me a mini heart attack. Despite that, I still give it an 8.5. I don't usually watch dramas that have a rare disease plot coz often times, things get awfully unrealistic. For this one, I did not even notice that. The story was well developed, the romance was built up so naturally (although there were a few awkward gaps/editing mistakes - they are forgivable!). The two main characters are both strong willed and wont let others bully them, so I didnt even mind the antagonists' plots against them. I was also quite surprised at how well both leads have acted their characters out (considering this was ML's first project and FL's first lead role). I would be glad if they made a second season. I wasnt prepared for that ending, really. We also need to see what happens to the support roles' characters ❤
