It’s worth reading, but it’s not for everyone.
I think it is worth an afternoon to read The Unwanted Roommate manga. I would recommend you take a read through the first volume before buying it from somewhere if you don’t have access to find free copies on the internet. Be warned that this manga doesn’t align with the culture values of America, so some readers may not be able to relate at all while others can very personally feel what Chihiro is experiencing right alongside her as they identify with her anger and frustration. There are many ways in which this manga could offend readers, but because we lack cultural context on how Japan treats or deals with these kinds of issues.
