Rika (Tsubaki Kanari) remarried Makoto, who had lost his first wife. Having lost her parents at an early age and continued to live in poverty, Rika was able to achieve a stable life by marrying the wealthy Makoto.

When Yuko wasn't looking, she would sneak around with journalist Yuji, claiming to be attending a painting class. One day, Rika saw a positive tweet on her blog, and as the tweet looked exactly like her, a plan came to her mind...
