he can't see our ears

After an accident, he said he couldn’t see our ears. [Warning: No.1 said] A yacht in a coastal city was missing. There were originally ten people on board. The search and rescue personnel found the empty boat and found a survivor in the nearby waters .Survivors have unexplained trauma and no specific memory of the incident.The survivor is "my" half-brother.Due to changes in my family when I was a child, my eldest brother raised me when I was young. After I became an adult, we didn't see each other for many years.I don't understand what's going on for a while.In short, the eldest brother said, he could not see our ears. ================================== Other introductions: The protagonist is a pair of brothers, the story is about family love (maybe there is no family love) , Strictly speaking, it’s a story about observing the disease) The story may be a bit cheesy, but it’s okay, there is no such thing as a god system, and the full text is not disgusting. The more lingering (?) is slower and less exciting, it is recommended to read when you have free time
