Alright, to make up for the description not being available I will give a bit more information then usual in my review.

So the story follows the MC a boy in the later years of middle school. He comes home from school and starts relaxing for a bit, only for his sister and her two friends to burst into his room in an attempt to catch him "enjoying some alone time." Failing they search his room for adult DVD's and books, finding some, and putting on one of the DVD's to... more>> watch. Dissatisfied with the mosaic they turn their sight to the only male in the room.

So, starts the novel. The story takes place over many years, starting with the MC in junior high school, to high school, college, and adult life. Most of the novel takes place at home, namely in the MC's room, with very little school aspects at all.

The MC's has 5 main girls, the 3 at the start, 1 introduced in high school, and the final introduced in college. Of all the girl's his GF which allows/supports the polygamy actually has the second least amount of chapter appearances besides the girl introduced in the college arc towards the end of the novel.

Alright now onto the smut and stuff that could be potential deal breakers for some people. Besides the initial few chapters most of the smut is one on one. There isn't any big group act with the MC, the only big group thing is a few chapters of 4 of the girls in a bit of a yuri situation where the MC doesn't take part in. He is there, just doesn't join them.

Besides those yuri chapters mentioned above, no others take place. It is said that the girls do stuff with each other, without the MC, it just never really shown. Of the girls 1 gets married to someone not the MC and regularly cheats on her husband with MC both while dating and while pregnant. 1 other girl dates a few times but during the relationships also regularly cheats on her boyfriends with the MC, before stopping dating other people altogether. The other 3 only interact with the MC or the other girls.

I don't think I'm forgetting anything else/to important. Overall I think the novel fluctuates between 3-4 stars, being more good then bad. I think the weakest link is the GF personally, only there to claim the role and allow the polygamy. Not having a big group event with the MC also seems like a missed opportunity, as besides the first few chapters the most he gets is 2 girls at the same time. <<less
