Natsumi and Miyuki have prepared to fix Ken a meal but, when they get to his house, there's a young woman waiting there for him.  All is not what it looks like though since she is to be his new mother - at the young age of 20.  All she needs in order to marry Ken's father is for him to call her "Mom".  That is not as easy as it sounds, though - especially with all of the rumors going around Bokuto Station.
