Yu-san is my older brother's classmate, and my senior when I was a student. She had always had a one-sided admiration for Yu-san, who was kind to me, who was shy and dull unlike her older brother. She, but she, she never thought she would marry her brother... She ended up staying at her brother's couple's house for job hunting, but she has mixed feelings. At that time, she couldn't give it to Yu-san while writing her thoughts on it, and since she saw the letter she had without throwing it away, Yu-san and I, who had been longing for a long time, had sex many times.
