This anime is a POV ecchi anime. The best thing that I can liken it too is Pillow Boys, Makura no Dashi, where it is a POV anime offering you multiple bishounen to cuddle up too at night.
This POV follows the protagonist and his story with 3 girls in his apartment. The next door neighbor, his younger sister and your childhood friend. Each story is developed separately and the time line is uncertain.
I don’t mind Ecchi, but this anime has a long way to go. The camera angles make no sense for a POV anime. The stories with each girl is weak and it is solely in it for the ecchi. Each episode is only 4 minutes long, so you can watch it yourself and make your decision.
