It is rare for anyone like Mizuno to have a grandson who cares about him and is dedicated to him. When he just heard that his aunt was sick, he hurriedly quit his job and quickly brought things to his house to take care of his aunt. The relationship between the two must have been very close and full of affection from the past, so the nephew took such actions. He did all the chores in the house for his aunt and even took off each shirt and underwear so that he could easily wipe her body. Not only that, he also took advantage of the time when his aunt was asleep because he was tired, he took incest and had sex with the desire to help her quickly recover from the disease. What a kind grandchild.
