Hmmm... Many people trying to guess if Jimi-sensei has trauma from not helping a student in the past who was raped, but in the first chapter he literally fakes that he was about to get raped by Momo, and I definitely think that someone who has a trauma of that wouldn't use that tactic... And also Ch. 5 the last pages, saying he's probably a cold-blooded murderer, but in this chapter, it says he's more of a cowardly murderer... Either the Author is bamboozling us or he's just bad at keeping things consistent
