Due to a sudden transfer from the Sendai branch to Tokyo, Tsuyoshi found himself in disarray, struggling to settle into his new life. Just as he was overwhelmed, his former department chief—who had kindly mentored him during his rookie days—offered, "You can stay at my place until you find a home." The chief lived in a two-family house with an available room. Grateful for his kindness, Tsuyoshi moved in, yet a quiet concern lingered in his mind. He had heard rumors that the chief's wife was exceptionally beautiful. Little did he know, her presence would soon stir unexpected emotions within him.
