I must say that all that I wrote on my review about the series Onegai teacher applies to this OVA. There is no significant change. I thought the animation was a bit of a step down from the series, though. BUT nothing dramatic. Kazami sensei's mom is still a "WTF?!" character to me. But there is nothing really bad to say about this OVA. Overall I really enjoyed this OVA it was a nice closure for the series and very fulfilling. I'm not an ecchi fan, but I actually like that we get to see Kei and Mizuho relationship get deeper ( I also enjoyed Kei finallycalling his wife by her name).
