First off, I'd like to say, I reallllllly hope they come out with an Age of Youth 3!
If you've watched the first season, you will know that two of the main actresses are no longer in the show. One appears once or twice over the season while the other has been switched for a new actress. This annoyed me when I first heard it but I was surprised at how much it actually bothered me the further i got into the show. The hints of humour at the actresses new appearance helped my opinion of it greatly.
The music in this show is incredible! I have downloaded the entire soundtrack, it's that good.
The story is generally really good and mostly relatable, especially as a student in an all girls flat. Sometimes things aren't totally explained in the drama, this allows you to think about it, but I think it wasn't used well in all cases. I like that in the drama things do not end "Happily Ever After" or the complete opposite of this. It somewhere in the middle sticking to it slice of life genre very well.
I probably will watch this again, especially if they bring out a new season!
