U see, im always tempted to dislike characters like Mu mu. But tbh, i myself know is a very hypocritical feeling. Anyone would at least do as much as she did so far to try to keep hold of some hope. Unless she does something to harm Birdie in any way i can only feel pity. She liked him for a long time being satisfied with just being his "pal" until was already too late.
But damn this 2 are too cute. Also, it'll still take a very long time for progress to be noticeable.
