Blood memoriese

My name is Kaito Hiroshi. I am 16 years old and in the 11th grade. My life was going perfectly normal until the day of that accident—the day I lost my family.
When I was 7 years old, we went to the beach with my family. I remember having so much fun. My mom and dad were sitting in small shaded pavilions near the shore, while I was playing with my little sister, Yuki. Everything was normal. But when we returned home, things started to change.
As we arrived home, my dad received a phone call before we got out of the car. After speaking for a while, his face turned red, and there was fear in his eyes. He told us not to get out of the car, started the engine again, and we hit the road. On the way, my dad asked my mom, “Is there a black car behind us?” My mom turned around and, with a trembling voice, replied, “Yes.”
I was very tired and sleepy. I remember my dad suddenly turning into a narrow street on the side of the road. After that, we were on the move again, and I fell asleep. But I faintly heard the sound of a car door opening and closing.
When I woke up, I heard ambulance sirens. People had gathered around me, and blood was dripping from my forehead. It stung a little, but I didn’t feel much pain at first because of the shock.
When I turned my head to the right, I saw the scene I can never forget, the one that haunts my dreams every night. A massive truck had crashed into our car. My dad was lying under a white sheet. My mom’s lower body was gone; she was lying in a pool of blood. They soon covered her as well. I hadn’t seen my sister until I turned my head to the other side and realized that she, too, was under a sheet.
I was in the ambulance. When the police officers and paramedics realized I was awake, they came to me immediately. A female doctor hugged me tightly to shield me from seeing anything and carried me away from the accident scene. But I had already seen everything.
They took me to the hospital first. At the hospital entrance, there was an old, charismatic man wearing a hat that partially covered his face. As the doctors were about to take me to a room, he came close, placed his hand on my shoulder, and walked away.
Shortly after I entered the hospital, my aunt (hana ) arrived, running. When she saw me, she cried sincerely, hugged me, and said, “Don’t worry, I’ll protect you.” I didn’t understand what she meant at the time.
I knew my family was gone, but I wanted to react. Like every child, I wanted to cry, but the scene I had witnessed kept my emotions locked inside.
The next day, we left the hospital and went to my aunt’s house. She had packed her belongings. We took only two bags with us and got on a train heading to an unknown destination for me. Throughout the journey, my aunt tried to comfort me, but all I could see in my mind was the accident scene
