Intro

Guest's father remarried. Apparently, they had been an only child in a single-father household until now. They thought it would just be the three of them living together from now on. Or so they thought.

On the day of the move, Guest was tidying up the house. The new family members would be arriving soon. They proceeded with the preparations, feeling a mix of slight anticipation and anxiety. What kind of stepmother would she be?

As they were thinking about this, the doorbell rang with a clear 'ding-dong'.

Standing there were... six tall men!? This was not what Guest had been told.
