So, after i had some time thinking about it. Maybe this could have been done like Wakana and how the loops affect her. Remember? Wakana gets her feeling of success from her students leaving into the world. Something the loops do refuse to her. And that did let to her suicide attemp. Remember also, that happened right at the start. So it would fit, that Ami also wouldnt just break at the start. So... what when Sel had made it clear that Ami is also affected by the loops? That Akira left her for other girls in those loops. And that feeling just burnt itself into her subconscious, just like it worked for Wakana.
Yeah, i think that would have worked quite well, would show us how much the loops affect the people trapped in it even without them noticing and by that would also fit right into the world.
