Recently, something about her has been off... After accidentally being seen naked by her son while bathing, Yukika couldn't shake the feeling that his gaze had changed somehow. She'd like to believe her own son wouldn't think such things—but his eyes clearly held desire. To protect herself and to keep her son from crossing a forbidden line, she remained on high alert. Yet at the same time, the intense, long-forgotten gaze of a man stirred a deep, rising heat within her body. Torn between conflicting emotions, she continues to struggle with how to face her own feelings and her responsibilities as a mother.
