Koharu Suzumura and Minato Matsuki are a young couple who finally achieve their dream of living together after meeting online and falling for each other instantly, despite a ten-year age gap. The story follows their everyday life as two women in a same-sex relationship, navigating both the sweet, mundane moments of cohabitation and the unique social hurdles they face. Their love for each other is depicted as immense and resilient, making light of the walls society sometimes places before them. The narrative is composed of episodic, real-life-inspired vignettes: celebrating a deadline with a massive feast, taking a late-night stroll, moving to a new home, handling the not-so-welcome milestone of a thirtieth birthday, and eventually introducing one another to their parents. As their relationship deepens, they begin to consider formal recognition of their bond through a partnership oath system, which brings them face to face with the legal limitations that still exist for same-sex couples in Japan. Through these small but significant events, the story paints an affectionate and candid portrait of a couple building a life together, highlighting both the joy and the quiet struggles that come with being a same-sex pair in a society where marriage equality is not yet fully realized. The series also touches on broadening their family circle, from deepening friendships to welcoming a new family member into their home.
