An ordinary high school student has lost his memory since his 18th birthday. He doesn't know who he is, nor does he know that his relatives and friends have changed their minds. Knowing that he met someone like him, a person who looked exactly the same in the same school, that person was perfect like a dummy, without any weaknesses. And his relatives and friends actually joined forces with this person to kill him. He discovered their secret and escaped, but found more "secrets". This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
