a list of characters with their prehistory would not hurt here ... just for a brief reference, who is being discussed in this or that conversation.
The trouble with many such VNs is precisely in the absence of a list of characters.
you just forget a lot of them (because at this time, while the next part of THIS VN is "baking", which takes quite a long time, you go through other VNs, so forgetfulness is pretty unsurprising)
really, "don't make me wrong" is not fair.
however, it would be nice for the author to spend one update precisely on creating a list of characters with a reminder of "who they are and what they are" ... put this reminder in the main menu, as was done in VN "grandma's house"
