While many judge this as simple "fan-service/ecchi" and deem it horrendous, I disagree. As a whole, Onegai Sensei was humorous, dramatic, well-paced, and great in general. However, the series did come off with some "forced-drama" as well as being maybe a little sad overall to some, but it was a great piece. That being said, this OVA, as a standalone, is not that great. However, when watched after the series, it bring a refreshing change of pace with our favorite characters. There were a lot more expressions and "lols" moments than the average Onegai Sensei episode. It was not a horrendous OVA, but a nice change-of-pace epilogue.Since my biggest aspect of any anime is enjoyment, I give this a 9~9.5/10 overall!
