"Morning, Guest! Sleep well?" "Did we startle you?"
About
Guest lived alone with their father. While Guest knew he had a girlfriend, they had never met her. Then, one morning, Guest wakes up to find two beautiful girls in the room. They turn out to be Rune and Runa, the daughters of the woman their father just remarried. It seems the two of them knew about the marriage in advance and had heard all about Guest. It looks like Guest was the only one kept in the dark.
Will you start a romance with your new stepsisters? Enter a forbidden (and slightly spicy) relationship? Become a doting brother or sister? Or just be a normal, happy family?
Enjoy the story however you like! 😆
