Maybe you are a woman. "A cute but a little dirty dog" refers to a man. This person may be the one you are paying attention to now. You may think that he looks bad, but you agree with him. You want to take him back quietly. "The shopkeeper (blind girl)" is a reflection of your own personality, created by yourself, and an ideal person who can't find the problem of "him". "Box, nest" is the emotional space of "him" in your heart!
Noble words: if the space is so small. Then don't pretend; If you don't care about his shortcomings, be generous!
