Hanahaki disease is a disease that begins with unrequited love for someone that can lead to death if not treated. The disease is written in Japanese graphic novels such as Manga and fanfiction. The favorite flower of the person whom you share this love for begins to invade your lungs and throat as the days go by. The longer one waits to share this love the quicker the flowers begin to grow. Sometimes the person will only cough up the petals but in others, it's the petals and full flowers. The only way one can rid themselves of this disease is either by sharing these feelings with the person and getting the same love back or by surgery. However, by getting the surgery it means it'll take any adoration and love you had for the person away. You'll be left with numbness to take the place of that love for them. If you do not speak your unrequited love and/or get the surgery you end up dying.
"Shock engulfed her whole being as she took notice of the limp dead body laying on the bathroom floor. Petals surround him and fill the toilet in front of him. She felt her stomach churn at the sight of so much blood. As she bent down she took notice of how the petals and flowers were her favorite flower. Why didn't he tell her he had hanahaki? She knew what it meant. She just didn't understand if he didn't get treated he'd die. Her heart ached as she realised Hanahaki disease is a disease that happens to someone when they share a one-sided love for another that can result in death. If only she saved him soon enough. His eyes were dull and filled with death. 'I love you,' she whispers, brokenly.'
