For those who keep giving this film negative reviews, sorry to say but you are biased and bitter. Because this drama is so far one of the best kdramas I've watched, this is coming from someone who has watched over 200 kdramas. You're a fan of the actress from the first season and not the storyline if you hate this drama.
I've rewatched this drama over 30 times and what amazes me it's I've never gotten bored of it. Every time I rewatch it feels like a new drama. I don't know why anyone who claim the plot is bad when it's literally just a continuation of the story which was split into two parts. Without part 2 I would never had understood the storyline. I also love the message the writers were conveying "LOVE SOMEONE BASED ON THEIR SOUL NOT APPEARANCE".
In conclusion Awesome and Amazing. Well written and amazing chemistry and cinematography
