As a man of many neuroses; disinfecting his surroundings and making sure everything is at a perfect angle, Han Bi Soo is so used to writing in his designated writing room that he can't seem to write anywhere else. So he enters into a contract with Joo In, to be allowed to use that room 24/7, on the condition that he calls her master. (Source: kortkrachtig at MyDramaList)
