I've been playing this game for like 3 hour and I got this ending which suppose to be the end of the game, she started to say good bye before leaving the exit, for me which very nice of her.
Also spoiler alert! after we having merried kind of stuff like that... you know what I mean, if you haven't heard about her ex - boyfriend kill her, she even told me about her secret that when she get mad or started to have knife on her she said "that not me that my dark side or her psychopath something like that, if her eyes is getting red it mean that her dark side. Thats the reason why if you leave she will attack you also...
I don't really play Yandere that much because I only saw this on yt that it getting recommended, but hey this is actually a good game and I kinda like this stuff. I hope u will make a full version of it, this is still a demo of course, ty for making this game XD hopefuly it will be improve in the furture. haha.
