I'm loving this so far! Though there's one "Bad End" that felt kind of abrupt. (Spoilers for Day 3)
I was going for a "Pro-Ren" playthrough, picking choices specifically to make him happy, spending as much time with him as possible, and in general either reacting positively to his odd behavior or waving it off. With this in mind, I refused to go out with Teo and Co., thinking I'd avoid making Ren jealous since he wasn't going to be there.
Here's where I got confused. After Leon calls and I refuse again, things started glitching out and I got a "Bad End". The thing is, Ren was claiming I was avoiding him. I replayed and agreed this time so I ran into Ren again, but it was after the outing with friends. This "Bad End" just feels misplaced because I made no choice to actively avoid or evade Ren since he wasn't part of the conversation until after agreeing (Angel mentions the possibility of seeing Ren).
Other than this though, I've loved everything in this demo and I can't wait for more XD
