Our guy got a no name game in the mail. When he played it, he end up in a mansion where 3 maids(big, middle, small) work for him. Now, waking up in the morning by his real world childhood girl, he attend class and can chase her or another school girl. Back home after school, he plays his maid game. If he manage to win a maid, she will be with him one way or another.
