Sekan Shirazuna Doukyuusei wo, Kaukoto ni Narimashite.

Arisa Sanaka is a naive, sheltered girl, the daughter of a famous film director. She seemed far out of reach, but I, Yukito Kurosawa, an ordinary classmate, "picked her up" and took her in to live with my sister in our house. "I've decided to run away from home. I might be willing to be picked up by you, Kurosawa-kun." For some reason, even my sister got into the act, making her wear a dog-eared maid outfit. And so began our daily life with Arisa....... She wakes me up in the morning, helps with the housework, goes to the riverside in the swimsuit I chose for her, and offers me a lap pillow in her pajamas at night. "Would you pat my head as a reward! Master-sama?" At school, she's the "unattainable flower," but at home, she's a "dog-eared girl looking for headpats." This is a romantic comedy about living together with a girl that is so sweet you'll almost melt. (Source: Kadokawa, translated)
