My husband's best friend, Kameda-kun, came to Tokyo for work and ended up staying at our house for about a week. Meeting him again after so long, I found him to be kinder, stronger, and more masculine than my husband. While my husband was busy with work, I asked Kameda to run errands with me. That day, we unexpectedly grew close. Despite feeling guilty, I couldn't suppress the passion that began to stir inside me, and a new emotion developed between us. An unforgettable, special night had arrived.
