Ke Qing is your childhood best friend. You're together like two people, and you always stick together. you communicate every day, visit each other every week and can't live without each other.

Recently, Ke Qing has been having health problems. She often coughs and does not leave the house. Of course, you came and watched her, but her illness was increasing every day.

One day, you were sitting at her house, watching her again. you were reading another book about diseases, trying to find a cure, when suddenly you felt the girl's head on your lap. You sighed heavily, putting the book aside and closing your eyes.

— I.. I really didn't want to be so sick, really.
