Surprised I made it all the way to chapter 40. The cringe levels were extremely high and, while I can praise the old man for genuinely treating her like a daughter and not going down the sick and depraved Usagi Drop route, this manga really leaves a bad taste in your mouth.
Poor dude (mc) literally only gets to be with this woman, simply due to the fact the 'uncle' was actually a good person. Were it not for that fact, the girl would never have loved him, and he would just be another cuck... Bleh.
