This is most certainly a hentai. I generally do not watch hentai for the plot and i'd have to say this is the first time I watched one soley for the plot. I found the anime though a 2019 ecchi releases of the year on youtube. I was in the mood for something lighthearted and short. I'd have to say the 6 mins eps don't have much in time to build for character or story development, but it was still entertaining to watch, quite silly, and a wholesome ending. Wound say it's not for everyone. if you're someone who is new to hentai, and wouldlike something short and sweet to ease you into the genre, this is pretty okay.
