Mai tells her boyfriend her mother is remarrying, her mom is happy to be finding love again, her new partner has a son too just like she has a daughter; Mai is happy for her mom so she will go along with the new marriage, ready to get along with her new father and big brother. The boyfriend is happy for her new family development, but he is kinda worried about she moving into a new house where she is suddenly with a guy older than her hanging around so close, he might not see her a sibling, but as a girl. Mai shushes him, however, telling him to be understanding of the situation both her and the new big bro are in, there will be nothing to worry about, Mai will always belong to her boyfriend.

Then the newly formed family gather, mom is happy, daughter is supporting, dad is eager, but son seems a little uninterested, dad asks for some patience for his son's behavior, the divorce with his mother was a little messy and his studies intensified for the upcoming exams; a while after big bro Takuya comes out clear to his new younger sister that he is mad with his dad for remarrying, he wasn't previously consulted or asked his opinion, he won't keep silent, he will raise a scene in front of his father and new mom in hopes of ending this relationship, but Mai pleads him to stop, she wants to get along so her mom stays happy with the new husband she seems to love so much and she honestly wants to nurture the boy like her own son, little sis says she will do anything to make him happy.

Thus the devilish Takuya enacts his plan, sure he will try to get along, but he makes Mai promise to follow what he has in mind, and that is she will become his personal sex slave. Mai cannot believe this, but she has to make sure her mom is happy with a new family so despite some protest she goes along with it; as they live their days together she sees Takuya honestly getting close to her mom like a dutiful son, everyone looks happy so she has to endure.
