I loved A-Teen Season 1 to death, and was super excited for Season 2. Even though I turned out to quite enjoy it, I don't think I loved it as much as the first season, for multiple reasons.

Firstly, there was barely any Do Ha-Na! Even though romance-wise I didn't care about her plot that much, I loved her as an individual character, and without her, I felt like the series also focused a lot less on friendship and sismance.

Secondly, I felt like there were so many questions still left unanswered from Season 1! That girl that Shi-Woo used to know, for example.

Thirdly, I was honestly annoyed by Bo Ram's mindset and lack of support for Ki-Hyun at times—I don't think any of that was sufficiently addressed.

Fourthly, I liked Joo-Ha as a character, but I don't know if it's just because he's new and I haven't warmed up to him completely yet (especially since we don't know much about him at all, other than his parents being MIA), but I just didn't care much for the relationship between him and Kim Ha-Na.

Overall, though, I enjoyed the parallels to the first season, and that we got progress for some plots, like

I'll also admit that I absolutely HATED Ah-Hyun at first, but now she's become my favorite in the cast, and I'm praying for a Season 3 so we get more of her and Min.
