HanaHaki disease: A (fictional) illness in which a person who has unreqitted love for another coughs up blood and flowers. There are 2 cures, the other person falling inlove as well, or a surgery to remove the flower plant from their lungs, this surgery causes them to lose all memories and feelings of affection for the person they love. Additons for my AU:people are born with the flower plant roots in their lungs, the more they fall in love with the person who doesnt requit the feelings, the more the plant grows.
