The harem is, of course, funny, but in games where there are interesting characters, I’m more interested in the “one gentleman - one lady” ending. And in the SotF all the characters, one way or another, are interesting. Abby is a wonderful girl, why brainwash her? The main character will be happy with a girl like her. It is more interesting for me to learn how the relationship of the main character with the female character will develop if the player chooses to be with only one.
Marsha has already admitted that she could fall in love with the protagonist. Will the main character be able to convince her to be only with him and live as a family? Does the main character have a future with Samantha? and so on
