I want a fic where it's like, at the beginning, Asa has trouble standing sometimes. Like every now and then, his legs will feel weak and it makes him lean on the closest thing near him. At the beginning, it's not that big of a problem. But throughout the fic, it gets worse, but the reader doesn't realize until far, far into the fic when it's explicitly mentioned by Asa falling and not being able to get up.

Throughout the fic, Asa's leg problems isn't brought up a whole lot, except for a couple of times. But he's describe as always leaning on something or sitting down more than he normally does, but it's played off as something non-important and not brought to attention
