Kou has been pestered with a dream about someone he does not even know at all. On his dream, that person confesses to him. But Kou does not understand why the person felt very familiar to him, and why he has this unexplainable feeling of longing for someone who has been so far gone even though he have not experienced losing someone ever as far as he knew. Then, Nene introduces Kou to some random 'cute' guy she just met recently. They met when the boy proposed of taking good photos of her one day on the school campus just because he find her cute. Turns out, the boy was also Kou's transferee classmate, Mitsuba Sousuke, an obnoxiously noisy person as Kou describes. Mitsuba gave off a good first impression on Kou but broke it anyway when Kou realises how noisy and annoying Mitsuba was to him. As time goes by, Kou started to notice things about Mitsuba that are too good to be just coincidences. Kou voiced out his concern to his friends, especially Yashiro. The two then began to investigate well and as their suspicion grew and grew, it didn't turned out well, especially for Kou. And in the end, with the help of School Mystery No.1, which was the Clock Keepers, Kou made a leap and set everything right.All Rights Reserved
