Yeah, the fortune teller has nothing to do with that. As for a possible harem ending, I guess everything is on the table atm, depending on how the Happy route develops and branches out. I mean, it could totally go everyway from there--"delayed" NTR (ie same ending as NTR, just starting later) should you screw it up, "pure" Happy (MC and Liz stay together and in love, but Liz keeps getting some from Matt on the side), NTS with MC getting more and more of a kink about having Liz tease guys/sharing her with them, harem with Liz and Sam (this would still need some groundwork, though--pretty sure Sam is still nowhere near such an option and the same could be said of Liz, but there's a certain picture at the end of the last update that seems to show we may be heading there as a possibility (ie the sleepover picture), which would be yummy), and also reverse harem with Liz living happily ever after with both MC and Matt (this one seems harder to figure out as Matt is such an asshole on each and every route, so imagining anything long term with him feels like a big nope, but you never know).
