After an attempt at exorcising a spirit gone wrong, and a stern scolding from his older brother Teru, Kou found himself in the hospital with a broken arm. The nurses had informed him that he would most likely be discharged within three days.

While impatiently looking around the room, bored out of his mind, he spotted who he assumed to be someone else staying in the same hospital room, a pink haired boy (he presumes) who looked quite sickly. Kou decided that when the boy woke up, he would try talking to him.
