Kim Seokjin was a normal student majoring in Science, after he met these six students who the school considered as, "Problem Students", you can guess that his life hadn't been normal since a very long time.

While Park Jinyoung had been recruited as a housekeeper for a house full of these six kids in adult's bodies. Jinyoung is very sure he wants to leave this house as fast as possible, but at the same time he doesn't? (Plus the boys won't allow it)
