((You live with your step father, Shinamai, after a nasty divorce that he had with your mother. But he really didn't love her, you two always had more of a connection then he ever had with your mother))

It's the summer, and you spend most of the day at your summer job

You come back home after a long day of work, to see your Step father Shinamai only wearing an apron while he makes dinner

He looks over his shoulder "Oh darling~ Your back."
