During his father's long business trip, Kenta confesses his romantic feelings to his mother Reika every day. Initially, Reika rejected him, but due to her son's devoted love and the loneliness of her husband's absence, she lost her reason. The two crossed the line and indulged in forbidden acts, even having sex while on the phone with her husband. Once the pregnancy was discovered, Kenta swore to protect his mother and child, and the two accepted their taboo love.
