Motoyan Yuubinkyokuin wa Karei Naru Kemono: Kousai 0-nichi de Kakure Onzoushi to Tawaman Doukyo!?

She's a plain, 27-year-old office lady, who got caught up with a drunk in front of her house. She was scared that he was going to force his way into her house, but a passing postal worker saved her. When she met him again later at a drinking party, he gave her a ride home when she got too drunk. She always thought of herself as an unlucky person, so she apologized to him for causing him trouble. But then he hugged her and they ended up having a one-night stand.... When the drunk next door started stalking her, he ended up taking her in to live with him. His house turns out to be a nice townhouse... and he told her she can repay him with her body. He feels so good it's driving her crazy, but is she really going to have to do it every day...?
