On the day designated for the sacrifice, Chizuru discovers the harsh reality. As tears stream silently down her face, she murmurs, "Just once... I wanted to hear you say you loved me." At that precise moment, Toshiro stands before her—her cherished one. What concealed emotions does he disclose to Chizuru? Thus unfolds the tale of an awkward yet sincere love between husband and wife, commencing at the break of dawn.
