Hmm, really short, and they hurryed to end this, coz pplz in Nihon didn´t like much this anime. I liked it, and it was really fun. Maybe, if gets good points outside Nihon maybe we can have Midori no Hibi 2! ^^
About the anime: From the first eps to the middle it´s really fun and a bit romantic... to the end less fun and more romance, it was strange, well, overall I liked it.
