Prologue:
A young man is all alone in the streets. Tired of running, he was breathing heavily. Then dizziness overcomes him. Then a shot of pain followed. He ended up clutching his chest in pain, leaning to the wall for support.
Flashback:
"You are Conan?" asked Ran with him. "Yes" answered the young man. "Why? Why did you hide the truth from me?" asked Ran in tears. "Because I don't want to put your life in danger. I can't let you die." explained the young man. "Am I not trustworthy that you can tell me?" asked Ran. "No Ran. If there would be one person that I would trust most, it would be you." said the young man. "I don't want to listen to your excuses Shinichi. I don't know if I could still trust you." said Ran. "Ran wait! Please listen to me." said the young man. "Shinichi you are so selfish because of your cases, our life was in danger. I hate you. I don't want to see you anymore. Get out of sight. Get out of my life. I don't love you anymore. Die, Shinichi, die!" shouted Ran before turning back leaving the young man behind.
End of flashback
Still clutching his chest in pain, the man said "Why am I still alive? Why am I still breathing? What's my reason for breathing? Ran, she is the only reason why I breathe. She is the only reason why I keep going. But now, she wants me dead. So what's the reason for living? Why am I breathing? Why? Why?" The man also known as Kudo Shinichi asked himself before closing his eyes for the last time. His blue eyes that shine in knowledge will never open up again. Never open up again.
