According to Mangaoh, a 10min long OVA of "Bungaku Shoujo" was announced to be released on December 26th. The OVA "'Bungaku Shoujo no Kyou no Oyatsu ~Hatsukoi~" will be bundled with the new volume of the novel titled "Bungaku Shoujo Minarai no, Shoushin". A trailer of the movie is also included as an extra.
I'm interested in seeing this movie and the OVA, but it depends on what genre its leaning more towards; slice of life or fantasy-ish. If its super slice of life then I don't think I'll end up watching it.
