AriaSoft has a lot to answer for with this one, violating the sanctity of the library for another game packed with big-eyed cuties waving their pants at the boys, and each other. There's a site up with lots of very smiley characters, way too perky for my tastes.
Based on a recent PC game, it's a love adventure with characters to explore set around the school library, perhaps were literary tastes are one of the selection criteria. It is due out next February, and is unlikely to make western librarians worried.
Between this and the more adult-looking Psychedelia of the Black Butterfly, it looks like these otome games will form the backbone of Vita releases next year, unless major Japanese developers drop some news soon.
