Are You Alone, Mister?

this was a good one,i doesnt understand why lots of people dont like it.its right that oniisan ohitori desu ka isnt the best hanime,but one of the best hanimes I've ever seen..Maybe animation level and reaction of the girl could have been better.And the thing that annoys me the most is man has no face,like bro you make a whole hentai and not adding a fcking face to man??reallyIm not a gooner btw,i just love watch hanime.This is my first review and my english is not that good,forgive me.Hanime is just 15 minutes,you wont miss much if you dont watch it
