Seriously, I've just seen a lot of people saying that this drama was boring. Actually, as for me, it wasn't.
Well the story was not that much deep, but it was actually why I liked it. Because it was totally refreshing. It was pleasant. No story of revenge, not that much conspiracy... Actually, it felt light, and I liked it because it didn't was heavy and annoying.
Well, as for the casting. Jung Yonghwa and Park Shin Hye assured it. It wasn't perfect, but it went well. I think it was even rather good. And Kang Minhyuk did a very good job, and you can't hate his character. The cast was good, according to me.
The music was pleasant too, and really present in all the drama. That was nice, even though I'm not a really great fan of Park Shin Hye's voice.
I think that this drama was really refreshing and nice.
