Domestic Girlfriend (Series rating: 9/10)

High school boy Natsu is hopelessly in love with his teacher, the charming, beautiful and energetic Hina. He doesn’t really have a shot at her and he knows, so, being depressed, he agrees to go to a mixer with his friends. There he meets a young girl who’s the same age as him named Rui. Rui is quiet and a bit odd. What’s odder is that after the mixer she takes him to a love hotel and asks him to have sex with her. Reluctantly, he agrees, being still sad about Hina. Once the deed is done they part ways. Flash forward a few days and Natso’s dad gives him the big news: he’s finally remarrying. His new wife is a lovely woman indeed. And she’s also Hina’s mother. And Rui’s mother. But wait, there’s more: they will now all live together. Yup, Natsuo gets to live with his crush, who is now his step-sister, and with his step-sister that he just slept with. What could possibly go wrong?

Oh my… this was an absolute dumpster-fire and I loved every second of it. You don’t often get to see such a cluster-fuck but when you do you have to take it all in. Natsuo’s not really bad kid, he just occasionally makes bad decision. Hina’s the same, only her decisions seem worse. It’s something when the normal one is Rui, a girl who seems to uninterested in anything that you’d think she was a robot sometimes. Add in two more lovely girls for our boy to choose (?) and you have the making of a fake harem anime. It looks like a harem anime, it’s set up like a harem anime, but ultimately it is not. Seriously, if you love trashy romances, this is amazing. Also, uncensored boobies. Also also, the most accurate representation of sex between two inexperienced teens: completely awkward.
The source is the US BD release. The JP BD won’t be out till August. Maybe. Also added a few scans from the manga where the extra uncensored scenes were first shown. It’s just a few illustrations. But I think you’ll like them. Subs are PGS from the BDs.
