I've come to realize, Marie cannot get over Sam, if you look into this work of art, you come to realise, Sam isn't here. Sam is only a figment of Marie's imagination. Yes we first play as Sam, but the final ending, it gives sort of a "oh, it was never real" type of vibe. The game overall presents grief and being unable to get over someone very well "I've moved on" was clearly an attempt from Marie to will Sam away, and with Sam stating it was only a year, that may be seen as Marie being unable to accept it's been that long. The text in red, it seems Marie cannot remember Sam very well, unable to remember just how he would act. Another viewpoint of this, Sam is forever stuck in this world. The red text could show he's losing himself, and his unhealthy obsession with Marie could show that he's trying to cling onto his past. I realized, Marie, she was never alive while staying with Sam, showing either, Sam is like a parasite, slowly killing Marie, or, he's Marie's pillar, that ends up breaking. Now this is an extremely lengthened way of me saying, god this game was harsh, but in a good way. Honestly, definitely one of the best games I've played
