If Sage doesnt have a ending with the mc, i wil be dissapointed, hope not.
I have very different ide for Sage and Jill, but luckily for people's I'm not the one who making the game. I honestly say, even 50 chapter wouldn't be enough for this game.
A full 4 year college experience would make this game the best adult visual novel all time. In that Game I would simply let Jill and Sage to move on, and removed from the game. It would be so cool and realistic, if, yes you gain great friends during scool life and etc etc, but Sage hase to move on with her life, so does jill, and MC still have to finsih it.
I don't want some cheesy ending of 10 years time jump, married to this or that girl etc etc, college is just one step of your life, you will fall in love more than once, you will have more than one soulmate etc etc.
one of the ending I would like is MC is the Dik president, Derek is the Vice president, and Derek bring in the new maggots telling them the history of the place, the Legend of the MC.
How he raised in the power, how he united everyone under his rule. and the rest is can be up to everyone own headcanon.
