Haruto Watari drags himself home after an exhausting day at work and finds the apartment in worse shape than he left it. He has no energy to deal with it. He collapses into bed and falls asleep immediately. The dream he has is nothing like his apartment: a luxurious Western mansion, beautifully appointed, and staffed by a beautiful maid named Seira whose sole purpose is to serve the master — brewing perfect black tea, providing comfort, attending to whatever ails him. The dream version of life is considerably better than the waking one.
