In my life, Yu Yu walked alone. In the first half of my life, I kept searching in confusion, and in the second half of my life, I continued to study the T virus for my daughter. However, it wasn't until she died that I realized that all this was just a trick of fate. Sometimes, I wish I was just James Marcus instead of Cone Zero. Unfortunately, I am. The light I am pursuing may have been swallowed up by darkness since I was 13 years old.
