I cannot think or comprehend of anything more cucked than befriending Susie. Honestly, think about it rationally. You are feeding, housing, opening up and character evolving a girl for at least 5 chapters solely so she can go and get ravaged by another monster. All the hard work you put into your beautiful little friend - reading her prophecies in the dark, making her go to church sermons, making sure she had food at all, teaching her to ACT, playing with her in Hometown. All of it has one simple result: her body is more enjoyable for Noelle.
Raised the perfect girl? Great. Who benefits? If you're lucky, a side character who had nothing to do with the way her character arc developed, who projects her dead sister on her. She gets to ravage her every forced cutcsene. She gets the benefits of her kind and sweet personality that came from the way you befriended her.
As a man who counts Susie as a friend, you are LITERALLY dedicating at least 7 years of your life simply to raise a girl for another monster to enjoy. It is the ULTIMATE AND FINAL cuck. Think about it logically.
