Kurohane is strange today too.

The protagonist, Fukamizu Shizu, has a childhood friend who is strikingly handsome, talented and beautiful, well-rounded in both academics and martial arts, has a great personality, and is popular with everyone. In contrast, the protagonist is utterly ordinary except for appearance. Moreover, because he is taciturn and his expression never changes, everyone finds him slightly unsettling. As usual, they're walking home together using their childhood friend privilege when suddenly he clutches his head and begins to suffer in pain... When he comes to, he starts saying things that make no sense... It seems the childhood friend, Kuroha, has become strange. ※This story is fiction and has no relation to any actual persons or organizations.
