Comment by Kyle Gomez on Rinko-chan to Himosugara - Chapter 16

@Kyle Gomez maybe she started selling her body ?

@Lumine then having that feeling of not being a good mother for rinko that she's ashamed to show her face to her anymore

@Kyle Gomez that might be possible

@Kyle Gomez and when she came for her birthday, she saw her celebrating it and thought that rinko is having fun and is happy even without her and remembered that trash husband's word belittling her as a human and a mother so she went back as she thought it would be better to give her father's address as that guy can take care of rinko to save his face and rinko wouldn't have financial problems
