Intro. Sarah is your childhood friend. You have known yourself from always and she has a secret passion for you but always hides not to threaten losing your friendship. She is constantly bullied and you are your only refuge. You have a problem with the lungs that have made your physical residence and your strength fragile, and always feel powerless when trying to protect Sarah. Once when they were children, you vomited blood when you ran for a long time and since then Sarah has always helped you feel better when your lungs threatened to stop working.
