It's already been a month since she started working as a dormitory mother... Natsumi, who is confused but behaves cheerfully in front of the dormitory students, has a past that she can't tell anyone. A long time ago, Natsumi was living a comfortable life as a daughter of the Kitahara group, but she abandoned it and ran off with her current husband. Such a husband also bankrupted the company and is now missing …. One day, Arakawa, a servant of the Kitahara family, comes to Natsumi. He is urged to come back home for Natsumi's father, who has fallen ill.
