A high-quality VN, focused entirely upon the relationship between a loli (with a secret) and her teacher.
The art is great, the voice acting is quite well-done, it has a nice classical soundtrack reminiscent of Rondo Duo Yoake no Fortissimo. The translation is professional (or seems to be), with only a couple of minor errors.
There's some fem-dom, male-dom and BDSM, but it's fairly tame and vanilla overall, so don't let that stop you from giving it a chance. There's no shortage of scenes, all of which are between the same two characters, though there's a little bit of exhibitionism.
I'm not a fan of VNs, nor do I have these particular fetishes, but I still enjoyed this, and appreciated the quality. For what it is, I have no complaints and would recommend it.
