Natsuno Fujii’s father has just remarried and he now has two new sisters. One, Rui Tachibana, was the girl he lost his virginity to, and the other is Hina Tachibana, Natsuno’s teacher and first love. Now, they all have to live together under one roof.

Domestic na Kanojo features a rather complicated familial relationship for Natsuo. He had developed a crush on his teacher Hina, but after a goukon, he ended up sleeping with another girl, Rui, who reminded Natsuo of Hina. However, his father remarries and it turns out that Rui and Hina are to become his new siblings. Wasn’t high school complicated enough? Right at the start of episode 1, I knew this anime was going to be like Kuzu no Honkai (Scum’s Wish), and if you do not agree with me, slap yourself because you aren’t paying attention. Everything about the main plot is exceedingly complicated. Then in episode 3, it turns out that Hina is the other woman in an affair with a married man. Natsuo makes this complicated by finally making his move on Hina, but man, it’s painful to watch them all self-destruct. What type of chaos can be added on top? Based on Kuzu no Honkai, anything can really happen.
