AMAZING! The beginning is kinda weird. And I definitely don't like that a 24 year old goes out with a high school student. But their relationship never goes into "dark territories" so to speak. If you don't like the start either, stick with the story for a bit. The character development is really good, and the last few chapters are perfect. This is definitely not one of those manga's that start of really good and have a bad ending - leaving you with things to be desired. It leaves you feeling satisfied, happy (and if you are cheesy enough, tingly all over :) ).
