Shima Shima by Sayaka Yamazaki 5 volumes - complete
Shio runs an aromatherapy salon which is also a front for "Striped Sheep". She provides young men as sleeping companion for women who have trouble sleeping. It's the literal meaning of sleeping just so you know. Anyway these young men also happens to live in her house. There's a live action tv adaptation too which I'm planning to watch as well.
