I know many won't like my comment, but i loved this drama till episode 20 ish and then had to FF a lot. the Slow burn suddenly got too slow. they focused so much on the events and character development that by the time they got together it got a little dull. That's one of the issues with Cdramas. They start strong but suddenly the writing gets twisted. I think those who binge won't have such issues but watching on-air and waiting for the leads to just kiss after more than 25 episodes is a lot. anyhow, a beautiful drama.
it's a very slow burn type. the lead's chemistry and development is also cute but them being together and kiss etc come around the last 3rd of the drama
