One of the overall best dramas i have ever watched. Though it is sadder than most and it made me tear up its overall just amazing Lee min-ki is a really good actor I’ve watched for awhile but the rest are top notch as well. I’m very impressed to say the least. And the music i still listen to it day to day it was amazing. I’m very impressed 10/10 would recommend. I cant quite recall but i don’t think the episode are too long. The overall rewatch rate I’ve watched it 16 times all ready. And I’m planning on watching it again.
