Thank you so much for writing this. Hanahaki disease has always been a touchy subject for me as a grey aroace. The idea of someone falling in love and then blaming me for making them sick, the fact that it is a trope that pretty much explicitly states "PLATONIC LOVE IS WORTHLESS HERE. FAMILIAL LOVE IS WORTHLESS HERE. IF YOU DON'T WANT TO KISS THIS PERSON YOU MIGHT AS WELL SIGN THEIR WILL AND TESTAMENT RIGHT NOW". The guilt that it inspires worse than the claims that already exist in the real world. That someone having a crush on you means you MUST give them a chance because if not you're a horrible human.
My favourite scene was the depiction of the cycle. Abuse, gifts, abuse, gifts, never speaking, never confronting, the sibling trying to help you see past the fear and repetition. It got to the point that my own memory irl began to blur. Haven't I read this already? How long has it been? Am I rewinding scenes? What is happening? Is this all there is?
And then Ending 4, gashkls god that took me out. I think I cried a bit. I need to sit with this for a while.
