Adjusting to college life is hard enough for most students, but ever since Banri Tada lost all his memories he's literally being haunted by the spirit of the person he was before the accident. And now that the Banri-that-is has fallen in love with Koko instead of Linda, the girl his old self was in love with, the ghost of the Banri-that-was is stepping up its efforts to sabotage his new relationship with every power at its disposal. Since past-Banri can sometimes take over present-Banri's body, the entire life new-Banri has built is now in imminent danger of being blown away like a house of cards in a whirlwind. That doesn't even take into account Linda and Koko's feelings, let alone those of Banri's friend, Mitsuo, who Koko was formerly in love with, but who now has a thing for Linda - at least when he isn't crushing on Chinami. And if that sounds confusing, it's nothing compared to how Banri feels as his old memories begin to resurface and the ultimate battle of Man vs. Himself escalates!
