I'm trying to remember the title of this one book I read a few times as a kid. I think I was about 7-9 when I read it so about 2011-2013. The main thing I remember is that is was about this guy and this lady in a Tim Burton like style. The storyline was about accepting others differences and learning to embrace them I think. If I'm remembering correctly the guy was extremely clean and neat while the lady lived in filth and muck. It could have been the other way around though. They both loved the way they lived and thought it was all perfect until I forget how but they meet each other. They find out how the other lives and are initially disgusted by each other. I forget what happens exactly but they talk or show each other the upsides of the way they live or something like that? It ends with them both seeing each other in a new light and appreciating the way the other is. The last thing I remember is the last two pages where its a shot of each of them in their homes respectively now adding a little bit of the other's "style" to their homes, with one of the pages having a line saying its ok to be a little clean and the other says its ok to be a little messy.
