[Synopsis]

When my father remarried, I unexpectedly had a new ''stepsister'' named Miu.
She never shows her emotions and only says ''yes''.
Because of her, my girlfriend, who I was hoping to get together with, dumped me.
''Take responsibility!''
''Yes.'' This is an immoral story about life with an obedient stepsister who only says ''yes'' no matter what I say .
