So, I saw a friend of mine playing the game recently and now I'm really tempted to buy it. My only question is, is there like a way to further a relationship with a specific character and have that result in like a unique ending (Ultimately an end game question not sure if the game is done yet but that won't stop me from buying, I'm probably gonna buy it either way) or just a kind of consequences or reason to specifically pay attention to one character?
Hey there! The game is still in progress, depending on your reading speed there's maybe 30-40 hours of content if you do all of every girl's content? But it's far from done.
In the long term, yes, each character will have their own ending (and some harem endings). Bringing someone you like along on quests has unique dialogue for them as well, varying by character and mission.
