Hanahaki Disease (花吐き病 (Japanese); 하나하키병 (Korean); 花吐病 (Chinese)) is a fictional disease in which the victim coughs up flower petals when they suffer from one-sided love. It ends when the beloved returns their feelings (romantic love only; strong friendship is not enough), or when the victim dies. It can be cured through surgical removal, but when the infection is removed, the victim's romantic feelings for their love also disappear.
The day Sero sat in his dorm alone, lost for breath, coughing until yellow petals poured from his mouth, that was the day he knew he was deep, too deep.
Other Warnings: contains big gae, a lot of angst, possible character death, cursing.
Katsuki realized that something was wrong with him on a random morning. His coughs became more forceful and harsh, and he suddenly felt something trying to climb into his chest until he coughed something out.
It was smooth, lovely cherry blossom petals that he caught in his cupped hands. Personally he couldn't bear the idea of having a disease, it's embarrassing. Getting love sick? Who on earth was he supposed to be in love with?
