One day, waking up, Haruna was shocked seeing "Haru" sleeping in her bed! Neither one of them knows why is "Haru" there.

Kanata was just about to leave but an invisible wall on the door prevents him from getting out of Haruna's room. Him being unable to leave, Haruna has no choice but to go to school while Kanata stayed in her room. At the train station, an old man tried to molest Haruna but Kanata saved her?! But this Kanata doesn't know Haruna!! Rushing back home, she saw the Kanata who slept in her room still there! What happened to Kanata's body? <<less
