Hello! I wanted to ask, what are the 11 endings? I really like this game, but I got Polar's route first and the whole thing just became  kind of a tear jerker for me so I don't want to do a full walkthrough haha

Hi Nunalto! Awww! I'm sorry Polar's route was...well..."polarizing". lol

Tbh, yes his route is probably one if, if not the most melancholy one. In terms of the endings themselves...there is no definitive document stating what happens in each. But I can tell you that there are 11 endings in total.

With most, if not all, of the LI's having a "best" and "good/OK" ending. There are bad ends, friendships ends as well as a funny joke ending. I hope you find one that pleases you more than the Polar one. =)
