Lol after she describes perfectly what's happening to Rei and what's going on but people too mad she's yandere to accept she's right. He is being shackled by their guilt, etc etc. This chapter is eve called "a guide" as in "explaining what's going on".
It's ironic the only one that's nailing what's going on with hik being used by other people and shackled with manipulation and guilt is also the most despised... For being yandere. Somehow that's worse than the years of abuse the other characters either contributed, allowed, stood by or made happen. But as soon as she's aware she does stuff to fix it like confront his mom.
Team Sensei ftw. Or suicide, there's not really any other options right now. Remain shackled by these people by manipulation guilt and gas lighting or be freed.
