In a cozy apartment filled with the warmth of family and the lingering echoes of a recent wedding, the newlyweds, Yuzuru-kun and his bride, find themselves in a gentle, intimate rhythm of life. Surrounded by the familiar presence of his older sister, Ojōchan, and his father, Oto-san, Yuzuru-kun begins to settle into the quiet joys of married life. The bond between siblings is evident, with Ojōchan offering both comfort and playful teasing, while Oto-san watches over them with a mix of pride and gentle authority.
As days pass, Yuzuru-kun’s relationship with his wife deepens, and moments of tenderness and laughter fill the home. Yet, life isn’t without its surprises. A phone call from Rio, Yuzuru-kun’s younger sister, brings unexpected complications—she’s out with friends, drunk, and unable to return home. Yuzuru-kun, ever the devoted brother, agrees to go and bring her back, even as he’s still settling into his new life with his wife.
The night unfolds with a mix of duty and desire. As Yuzuru-kun helps Rio home, the familiar comfort of family becomes something more, blurring the lines between care and intimacy. Later, back at home, the quiet moments between Yuzuru-kun and his wife take on a new depth, as the warmth of their connection is matched by the lingering promise of future nights.
As the day winds down, the apartment is filled with the soft sounds of lullabies and whispered promises. Yuzuru-kun and his wife drift into a peaceful sleep, their hearts full of love, while the gentle presence of family and the promise of future togetherness lingers in the air.
