Sure, I have "this bad of a memory" if I don't remember things like: "what is that Alyvia was unhappy about her relationship with her boyfriend", "what is the age of the mother again", "what did they have planned for the date coming in two days". It's either my memory is shit or you don't have a life.
Ok, but ... who gives a shit? I am not kidding, why do you think that those are vital pieces of information that you would need to remember for the next update.
Whatever Alyvia is angry with her boyfriend about, if it ever becomes important again, it will surely be mentioned in the dialogue.
Who cares how old exactly the mother is? It's a nice piece of worldbuilding, but why would you need that information while playing.
And whatever they planned for a date, either it comes up in the dialogue again or you will just find out ... when they have the date.
The true important pieces of information would be something like: "Why is mc worried about his mothers work", "Why does Viktoria hate the mc". And information like that comes up often enough in the story of the game and is pronounced enough that it is also very easy to remember.
