Watching Sumire practicing 'informality' over and over is enormously funny. She keeps stuttering over her boyfriend's name-- wanting to use his family name and trying really hard to be less formal in order to please him. It winds up making her stressed out and uncomfortable, which is, of course the opposite of what the guy was striving for when he suggested they speak less formally to each other! ( )

This one ends in quite a "cliffhanger", but unfortunately my local bookstore didn't have the very next volume. Luckily, a series like this doesn't change very much in one volume, and I was able to pick up reading with the next couple books. ( )
