Borrower of a Certain Age Concept
Aka tiny grandma and her giant grandson
Old lady borrower who maybe forgot where her home in the walls was, and also that a human lived there, so when she’s inevitably found by the human she can’t even afford to be scared and is like “ohh you have eyes like my grandson! what’s your name, young man??” so now the human’s got this like, 4-inch tall grandma figure in his life who still insists on pinching his cheeks despite him having to lean down and scolds him for his terrible eating habits and sure, maybe she calls him by the wrong name sometimes or forgets he’s a human at all—and maybe he’s never really had a connection with his own family either, maybe they even threw him out, and this love is unfamiliar—but man, the love is there now and it is strong.
