>>18142474Have you ever played Fate/Stay Night?
There's a part in the "Heaven's Feel" route where the main character and the main girl for that route are both going through some extremely bad shit, but they cope with it by simply not even acknowledging that it's happening to them until they have no choice but to do so.
Multiple people die, but they don't know those people, so they rationalize it away. The protagonist gets his fucking arm cut off and just walks home and says "yeah I got in a bit of a tussle don't worry about it." He's 90% sure that the girl he loves is a monster, but he refuses to let his conscious mind accept that.
Sometimes, people will simply do anything to allow themselves to continue living in routine.
