The story opens after a young female student kills herself by jumping off a balcony. It's soon discovered that she was in fact stabbed, and the room arranged to make it look like a suicide. And so we begin. A few minor details lead Detective Kanzo to suspect that Ryo, an enigmatic chef's assistant, knows more about her death. The two have run into each other by chance a few times, and each time left Kanzo with an uncomfortable feeling. Every clue that is revealed seems to lead to more questions about Ryo, his obsessive girlfriend, his callous and manipulative relations with several women, and about a painful memory from Kanzo's past.
