Resident Kanae apologist here!!
Ooouuuch this chapter did such an incredible job portraying what a shame spiral feels like.
You mess one thing up and suddenly every moment of shame and failure starts playing in your head one after the other. It's so easy to judge yourself and living at all as worthless if all you're thinking about is times when you suffered.
What should have been a moment of self-reflection and growth turns into a desire for punishment because of how inappropriately high the shame and stress levels become. We see this as she immediately repeats the verbal abuse she's recieved all her life and physically hurts herself in public, not even noticing anyone around her.
Important! She is not doing any of this on purpose! As she said, it all happens so automatically that she feels like it's the only way she can live. Unfortunately, there are no therapists in Japan apparently 🥲🥲🥲
