Hanahaki Sickness ((Japanese); (Korean); (Chinese)) is a hypothetical disease in which the sufferer of unrequited or one-sided love vomits or coughs up the petals and blooms of a flowering plant growing in their lungs, which will grow large enough to make breathing difficult if left untreated. Unless the victim’s sensations are returned or the plants are surgically removed, the sickness can endure anywhere from 2 weeks to 3 months, and in exceptional circumstances, up to 18 months, until the sufferer dies. In the lungs, there is no specific flower that blooms, however it might be the enamor’s favorite flower or color. Hanahaki can be treated by surgically removing the plants’ roots, but this procedure also removes the patient’s ability to love romantically. It may also be used to remove the patient’s feelings for and recollections of the person with whom he or she is enamored. It can also be treated by the victim’s sentiments being reciprocated. These aren’t feelings of friendship; they must be true feelings of love. If the victim believes the love is one-sided, they may acquire Hanahaki Disease, but they will be cured once the infatuated reciprocate the sentiments. Other symptoms include fever, excessive shaking, loss of appetite, low body temperature, and hallucinations, according to some sources. Even if the disease is healed, with or without surgery, lasting damage to the lungs might occur, and in rare circumstances, the sickness cannot be cured.
