You're right, this game is no fuck em all harem game. There are different endings planned, one of those
has a small harem of 3 girls (won't name anything here you might be able to guess and another ending will have
a perverted mother (she is not in the game yet) who has a daughter and they'll be okay with MC and daughter, so a happy sharing family tending to MCs needs
And yes, I see more ppl already hating on Karen, well... there is more to the story and the story will be told. Karen didn't become a Karen over nothing.
There will be a flashback scene in day 3 just to give more context
