A Madder Red.

7 years ago, Yoichi died in a traffic accident. His wife Ryoko did not receive compensation from her husband's death. She has since raised her son Junpei by herself. Junpei is now a middle school student. Ryoko also cares for her father-in-law, who lives in a nursing home and she also runs a cafe. Her care is in a difficult situation due to Covid-19, while Junpei experiences bullying at school.
