I loved it, but why did I get the bad end with the chimes n stuff? My only working theory is that it's down to me not flirting with the characters enough for them to like me, so i missed some interactions that could've saved me, but I always try to stay single on my first playthrough of any games like this (aroace for life!) so what's going on?
The story splits off into different routes depending on your love interest after Chapter 4! Basically, you lock in who you're romancing at the end there, or else you get the "bad ending". There are no platonic routes as this is a romance game. It's central to the narrative (each love interest has their own dedicated subplot), so there is no option not to pursue romance here.
