The Oneechan Maid Plan is dead before it even begun. Senchou's sister complained about her free Tokyo apartment being on the first floor and not getting enough sun so Marine told her to fuck off. Now poor old Marine's Papa can't bang Marine's ex-supervisor at all hours of the day in his own house because Marine's Sister will continue to cower in her bedroom lol
