College student Banri Tada who lost almost all of his previous memories from an accident is recently being haunted by the spirit of his past self. Now that Banri loves Koko instead of Linda, the girl his old self was in love with, the ghost of Banri’s past self is increasing its efforts to sabotage his new relationship by sometimes taking over current-Banri's body. The new life Banri built is now in danger of being taken away, which doesn’t even take into account Linda and Koko's feelings or how Banri feels, as more old memories are returning.
