Two people who love each other across time get thrown into the Genpei War, where that love becomes a liability instead of a refuge. The show treats its sci-fi hook not as spectacle but as the cruelest possible context for a romance: you can travel centuries, but you cannot save the person standing next to you from the violence closing in. It's a small story told in a compressed format, which means every moment has to count, and most of them do.

Katsumi and Sakura tumble through time into Japan's turbulent Heian period, landing in the middle of a brutal conflict between the Heike and Genji clans. Their modern knowledge and outsider perspective make them valuable commodities in a world torn by power struggles and ancient grudges. As they navigate court politics, warrior codes, and shifting allegiances, the couple discovers that their arrival wasn't random. Someone, or something, pulled them backward through the centuries for reasons that remain unclear. Caught between protecting their relationship and surviving in a hostile medieval landscape, Katsumi and Sakura must decide whether to hide their true origins or use their knowledge to reshape history. Every choice they make risks unraveling the timeline itself. The series balances intimate character moments against larger questions about destiny and free will: can two people from the future change the course of war, or are they simply pawns in a game orchestrated by forces beyond their understanding? Time becomes both their greatest weapon and their most dangerous enemy.
