I'm glad I didn't drop this after the first volume, because I've settled into the relaxing pace of this manga.
The four main girls have great chemistry, and it is just plain relaxing to read their drama-free interactions. There is also a secondary of young women senior to the four, who are either their cousin, or teachers, and their interactions with each other or with the younger girls are great to read, too.
This manga is just so relaxing, which can be soothing to the tired soul.
