Hey there!
Thank you so much for playing it and for your critique! Feedback is very important to me.
Putting myself in the shoes of the player/reader, I believe I can understand what you described.
I tried to make the two characters believable, but I also gave myself full creative freedom to make them way more intense than what you would expect for socially acceptable behavior.
Kien is a Yandere character. Sallie seems to be a person who avoids conflict (exactly as you described), but who experiences a great deception by someone she trusted and was developing a crush on. Her unexpected reaction to the truth is part of something that we also didn't know about her - she also has a dark side.
I'm sorry if you didn't like the ending. I know cliffhangers can be frustrating... I used to hate them when I was younger, until I found the charm in how they made me think of so many theories! lol
I hope you still had fun with the game! 😄
