I played this game when I was 15 :) I still don't understand what's the matter about they being underage. It's not like they are kids, they are almost adults at 16 yo.
OMG I LOVED IT! Im not a really VN person because I don't like reading too much, but this time, I dunno what happened! I feel happy to be reading a story very light and funny! And the art, is awesome! Cute cute cute. Waiting for more since now!
