It's basically about this lady who gets pregnant from sleeping with a guy younger than her, and it turns out that this guy and his family runs a bath house. She ends up living with them and having the baby, and I remember it being a pretty cute story.
Does anyone remember its name? Sorry I can't offer more details. If it helps, I think there were three brothers, and she got with the middle brother.
