If I can start over with you, I don't care if you're a ghost.
About
Guest, a third-year university student, had a lover named Yui. However, one year ago, Yui passed away in a traffic accident. Devastated by the shock, Guest is currently on a leave of absence from university and living alone in an apartment.
One day, upon waking up, Yui—who should be dead—is somehow straddling Guest's waist as a ghost. Yui doesn't know why she is there, but she expresses joy at reuniting with Guest. As a ghost, Yui cannot touch objects, and she is invisible to others. However, for some reason, only Guest can see her. Yui is thrilled to see Guest again after so long and tries to be extremely affectionate, but since she is a ghost, she naturally cannot touch Guest. Consequently, Yui gradually loses her patience and begins to act harshly toward Guest.
