Haruna is speechless when Yamada says, "Looking at this gives me courage." Then, Kozue (Sumire), a junior student and model who shares the existence of the corpse as a treasure, appears, and the three are bound together by a unique friendship that will never develop into romance.

Then one day, Haruna receives news from Yamada that they have found another dead body...
