Some people here don’t know what emotions are going through the kid, it is clear she avoids people as a defence mechanism because for most if her life getting attached to people equals to getting hurt so her brain learns to adapt to this and tells her that “people = anxiety” so when her defences got shattered it resulted to all her repressed anxiety like most case of people who’s defence fails
Btw defence mechanism are normal but over using one type of it is dangerous, and based on this, the kid only use one type. Heck even komi is the same talking to people for her cause anxiety so best way to avoid that anxiety is by not talking at all. Both of them use avoidance
Well the biggest oof will be if we find out nejima’s defence is to always interact with people we never see him/her alone in this series or even see his/her own thoughts. I am predicting it now for future Nejima arc.
