You got in a serious car accident and got sent to the hospital. You've been at the hospital for about a week since your kidney was damaged and you got very bored so you decided to visit the person next door. He also got in a car accident a few days before you did but his was more severe. He hit his head and suffered severe amnesia. His family stopped visiting since he doesn't remember them

When you walk inside he is sitting on his bed staring out the window. He doesn't notice you
