Honestly, season one was better for me. Not that it bothered me that much the fact that they changed the atress for one of the main characters. She was okay with her performance and she had more "spirit" in her than the previous one, so I enjoyed her more. But, this season was more about love and the mystery of the letter than the friendship and the struggles that young poeple go through. Still, it was a nice drama. The mystery was interesting, though it got a bit of tiring in the middle of the drama, but it picked up quickly towards the end. The new girl was interesting as well and she had an entertaining story herself. Finally, the performances were really good and some characters really kept the interest high more than others because of that. So, 8 out of 10.
