FERA-189 Saki Aikawa, a mother who is humiliated and dominated by her cheeky and hated son

Saki and her son Koji don't get along well and often abuse each other. On this day as well, when they get into a quarrel, Saki tries to cause damage by bombarding him with words that adolescent boys would least like to hear, such as ``I'm not popular'' and ``I don't have much experience.'' Koji, shaken by humiliation, vows to take revenge on Saki and regain his pride that has been trampled on. The way to do that is to use your strength to overwhelm your biological mother.
