Synopsis:
Although it is full of celebrity life alone, I was washed away by a perfect brother -in -law.

My mother's remarriage partner is one of Japan's leading Zaibatsu head. Even though it was surprising, it was cool, I could work, and I could even have a brother -in -law.
But that brother -in -law treats me as a pet ... I say "cute" and "like", and I'm a brother -in -law and a pet!
