"Hanaoka Yasuko never liked him."
"But to protect that woman, he's willing to kill another person—a cruel and cold-blooded method, filled with bloody obsession!"
"What kind of devilish love is this?"
"The most terrifying thing about Stone God is that to ensure absolute success, he went and confessed to top the crime. Now the police have identified Stone God as the one who killed Togashi, even if someone later discovers the real Togashi's body, it won't be exposed. No one would think that was actually Togashi's real body, because the Togashi case is already closed, unless Stone God himself appeals to overturn the case."
"Devotion?"
"No wonder the book is titled 'The Devotion of Suspect X'; this is using his own life to love this woman!"
"Why?"
"Even though the truth is now clear, the only thing I can't comprehend in this story is why Stone God would love Hanaoka Yasuko so much, even at the cost of his life—this is a death sentence!"
Of course, there's a reason why.
