I married a man who had a son with his ex-wife. My stepson Yuichi and I had a good relationship and a quiet life. However, our efforts to get pregnant never progressed, and I always felt a vague sense of dissatisfaction in my heart....... Then my husband was sent on a long business trip, and we began to live together. Around that time, as he grew closer to me, I began to feel a strange discomfort. But I couldn't stop it, I could only let it happen...
