The girl who was always by my mother's side—Mika Minamisawa. Her pure, innocent presence constantly stirred something deep inside me, even through the fabric of her school uniform. Marriage meant nothing to me. All I needed was a reason to keep living under the same roof. That was enough. Every morning when she appeared in the living room dressed in her uniform, my desire grew stronger. I'd deliberately brush past her in the hallway, sneak glimpses of her wrapped only in a towel after her bath, and spend every night lost in fantasy. As my mother began spending more time away, my actions grew bolder. I touched her gently, let her get used to my presence, slowly closing the gap between us. From the day I stripped off her uniform, Mika was no longer just a daughter to me. Even if she resisted with words, her heart and body already belonged to me. I was the first—the only one—who knew the moment she became a woman.
