a fictional (emphasis on fictional) disease, often used in fanfictions, where the victim regurgitates and coughs up flower petals when they suffer from unrequited love. The illness can only be cured through surgical removal, however any existing romantic feelings are also removed with the infection.
the "hanahaki disease" can't really be applied to real life because it's fictional, so no examples for it...sorry!
