This is a Christmas epilogue that actually remembers who these characters are four months later. Hazumu's caught between two people who love her, except now everyone's grown enough to sit with that without pretending it's a problem. The OVA doesn't resolve the triangle, it just lets you watch them exist together, aliens included, and somehow that's enough.
The holiday season transforms the lives of Hazumu, Yasuna, and Tomari as Christmas approaches four months after a life-altering event. Snow falls, decorations go up, and the three navigate their tangled feelings amid festive preparations. When Yasuna requests time alone, Hazumu finds herself caught between honoring that wish and seeking clarity about her own heart. She turns to Tomari, hoping for understanding and perhaps something more. The weight of unspoken emotions hangs heavy as both girls process what they mean to each other. Even the aliens who changed everything join the celebrations, adding their own brand of chaos to an already complicated situation. This OVA captures quiet moments between the chaos: stolen glances, hesitant conversations, and the vulnerability of admitting what you truly want. It's a study in how love doesn't always follow a straight path, especially when three people are involved and expectations collide with reality. The Christmas setting underscores themes of togetherness while each character grapples with loneliness and longing.
