I'm not sure if it was on chapter 43 but Bido and ml talk about his late wife and he told her that he knew that the person who killed his wife was the buzz cut guy. They finally have sex on chapter 44 and he told her a little bit of his past, that the person who he saw as his family was a murderer, and he had to live with that sin, but he didn't want that for bido. The next day after doing the deed ml told her that she should keep her luggage because they were going to move out. Ml gave Bido a key from a rented apartment and told her that she should go first because he got things to do. But we see at the end of the chapter that he has fuel storage in his house, so I think he's going to replicate what his protector did for him during his youth, he's gonna immolate himself for "bido's sake".
