The Share House's Secret Rule

A modern slice-of-life harem romcom with a mature 18+ edge, this ONA series is adapted from the manga by OUMA and produced by studio LEO. Directed by Junito Sasaki with series composition by Iruka Taichou, the series stars Kanade Ayase, Ryouta Ochi, and Momoka Hanaoka in a drama-driven story set in contemporary everyday life. Blending lighthearted romance with bold storytelling, this is a standout title for fans of adult romantic comedies.

The Share House's Secret Rule follows Ryouta Ochi, a young man who has just started university life and moves into a shared residence to begin a brand-new chapter. Far from an ordinary living arrangement, the share house turns out to be home to two remarkably beautiful women — Momoka Hanaoka and Kanade Ayase. As the three housemates settle into their daily routines under the same roof, an unusual agreement quietly takes shape between them: a single, unspoken rule that none of them dare reveal to the outside world. That rule? "If it's just for a minute, you can touch whatever you want." With this tantalizing promise hanging in the air, every corner of the share house becomes charged with sweet, irresistible temptation. What kind of cohabitation life awaits Ryouta behind each closed door?
