Sara can not feel pain. Nanami shows Sara around the hospital. At night, Sara knows Nanami is a patient and not a nurse. She also knows that she has been in a coma for the past 10 years since she got into the car accident at the age of 7. Sara is also surprised that she is still in a coma. She is having an out-of-body experience.
