The story
The story begins with Keita Suminoe, a male third-year junior-high school student studying for his high school entrance exams. He is living in a home with his older twin stepsisters, Ako and Riko, who share no blood relation to him, and they help him prepare for his exams. Even though he initially dislikes himself for it, he begins to become attracted to his two step-sisters, and his two parents encourage him to eventually get married to one of them.
What it’s like
Bright, glossy cel animation with saturated pastel colors, sunny daytime interiors, and the cramped, lived-in feel of a family home and a junior-high classroom. The comedy runs on exaggerated slapstick, rapid reaction shots, and sitcom-style mishaps, with a light, bouncy score and cheerful voice work that keeps the mood breezy. Its vibe is cheerful, flustered, and undemanding, the sort of thing to put on for an easy evening or as background while doing something else. Pacing is quick and episodic, with the romantic tension built from small domestic moments and running jokes rather than sustained drama. The central premise is incest-adjacent romance between a boy and his stepsisters, and the show leans into romantic and sexual fanservice, suggestive scenes, and flirtation throughout. There is no real violence, and the slapstick stays cartoonish, but the sexual content and the taboo premise are the main intensity, so it does not suit viewers seeking something gentle or nonsexual. It is best for fans of harem anime and teen romcom comedy who are comfortable with the premise and want lighthearted, playful romance with plenty of cheeky energy.
