Ashida Mamoru is a god-tier manga assistant but his habit of turning authors lazy has left him without a job. Luckily, one of his classmates from university happens to have a little sister who is a serialised manga author in need of an assistant.

This author, however, needs some... [i]handy stimulation to work.

Will Mamoru be able to keep it civil and professional? Is such a notion even possible in the first place under those conditions?
