Well this is what I found googling mura mura. Can't say it's what they meant for me to find but here we are. Certainly might make someone chuckle if they see mura mura and think of whatever this is.
I'm one of the few who likes Usagi Drop manga. Guess most people thinks I belong on a cross,
but I think the ending makes senses from context. Do I promote it? Nah, I wish she ended up with her childhood friend and him with the boy's mother. Do I think the manga is ruined because the author choose to end the story that way? Nope. As I said, the ending make sense and everyone around acts in a believable way. It's a good manga for me and no self-righteousness can change my opinion. Just want to get this out here as a devil advocate kinda way.
