Hanahaki Disease - an illness born from one-sided love, where the patient throws up and coughs flower petals when they suffer from one-sided love. The infection can be removed through surgery, but the feelings disappear along with the petals. It can be cured without side effects only when the feelings are returned. Acacia - secret love Yellow Carnation - rejection Hydrangea - heartlessness Marigold - grief Rose - love ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {One-sided!
