I'd say there has to be a harem ending except I've seen other games make you break up with all but 1-2 of your girlfriends. Which sucks, because instead of one happy ending you end up with like 8 mostly unhappy ones. It's possible a full harem might be new game+ only though.
everheard about sisterly lust?23 girls pregnant and you have a lot of kids.All of them help each other,working and live like usual,the only difference is when they feel horny,they either fuck the mc or fuck other girls..
But for this game,i cant say they unhappy..the harem ending are possible,like Evelyn can fuck Callie whenever she want,if she feel horny or something..Evelyn become bisexual eventhough just a moment ago she is into men.Everything is possible in this game,and id like to see that Advance lesson with Nell,there is an option to ask the lady of the house to join in for the blowjob/sex with you and Nell(which is not in game yet)Erato and Queen Fey,Nell with Primrose,Samarra with Evelyn or Evelyn,Callie with the nun.

it such a shame to let go some of them though,they all are so beautiful and such a waste of opportunity.
