Six months ago, I asked Kasumi, who lives nearby, to be a private tutor for my daughter, Mika...

Things she couldn't tell anyone, like her husband's infidelity... However, Kasumi, who had opened up to Kokoro and talked to me, saw me as a sexual object. And when I made Mika study on her own, she began to desire my body...
