Tsuyuri’s life is turned upside‑down when her cold, elite fiancé — a brilliant but aloof corporate heir named Kōichi — announces bluntly on their wedding day: “This is a loveless marriage.” Suddenly thrust into a strategic marriage for reasons neither of them fully expected, Tsuyuri decides to embrace her freedom and otaku lifestyle.

But fate has other plans. At a live event celebrating her favorite idol, she unexpectedly meets Kōichi there too — in an unrecognizable, casual form. Sparks fly as the awkwardness of marriage life collides with their real selves outside the corporate world.

What begins as a pragmatic union soon becomes a heartwarming romantic comedy — full of misunderstandings, sweet moments, and the slow but genuine connection between two very different otaku souls.
