@Psychronia I think that's the problem with a lot of manga (or stories) in general - because of exposition, and immersing the reader into a "new" world, a lot of characters act like things have only been happening a short while, or that problems are recent. It's a major flaw in many, many plots I've read, and one that isn't particularly easy to solve either (short of just throwing the reader into it without warning, but that's a skill that authors have to develop)
It's not limited to just events or problems either - sometimes, inexplicably, other characters will explain things to the MC as if it was their first time doing those things - just for exposition and "readersplaining", so to speak - even if, by all metrics, the MC should be even minimally aware of them. Some authors use the almighty "amnesia" plot device, but it's been so overdone that it's starting to seem lazy to me, somehow
