My beloved mother is getting remarried, and I, her son Yusuke, feel a pang in my chest at the sudden appearance of her new partner. Struggling to suppress my complicated emotions, I meet him anyway. Through our conversations and interactions, my possessiveness, loneliness, and deep attachment toward my mother grow stronger. I'm torn between the sense of loss at leaving the home I grew up in, the hope that my mother will be happy, and the fierce desire to keep her to myself. Amidst this turmoil, I gradually begin to see my mother as a woman. A poignant story of emotional conflict and inner struggle.
