It's been a year since we started living together with my mother-in-law and her two children, triggered by the death of my father-in-law. Today, my mother-in-law suddenly announced she wants to become a lingerie model. She had apparently applied without telling us and was informed of her acceptance afterward. My wife, learning of this, firmly opposed and ended the discussion. Although I was confused, that night I accidentally witnessed my mother-in-law, unable to give up, trying on lingerie through a gap in the room. I was instantly captivated by my mother-in-law's expression and posture, which I had never seen before.
