So to understand this anime you need to to get there are 2 versions the censored version which is a really great anime/And the uncensored version which is a good story hentai i will just talk more about the censored version it's 3-3:30 minutes episodes and the uncensored episodes are the same story but 4-5 minutes long because of the small hentai scenes
Censored Version:It's a really good love story anime which you can watch in a small amount of time like 30/40 minutes and you will certently enjoy it has a good story a good communication between the characters and of course a good ending.The story begins with a student Souji hating his teacher Nano but in reality he loves her and want to be with her.At the same time Nano's father friend wants her to marry his son Souichirou without even knowing him,at the interview/rantevu they had it turns out is it wasn't Souichirou but his younger simbling Souji.From there he confess to her and makes best at his side to make her love him too
Uncesored Version:It's a decent hentai but it has a love view even when you see the uncesored scenes you will feel the romance getting into you
To close up i think it's really and for the time it takes you it's pretty worth
Hope I helped from my point of view
