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. (

There are lots of variations on the setup, but in its basic form, this trope interacts with a lot of broader themes/plot devices, any of which could be reasons for its popularity:
-unrequited love literally kills you
-body horror
-color/flower symbolism
-uncomfortable confessions and misunderstandings
-sometimes leads to angst with a happy ending
-sometimes ends in tragedy
Unfortunately, for me, the most common formulation ("have your love returned, have surgery to remove the flowers and all memory of your loved one, or die") doesn't really work for me. Usually, when I'm in the mood to read something about "A loves B but thinks B will never love them back, but then, B actually does come to love A romantically, and they get together and live happily ever after, yay!" I don't need an added supernatural trope or raised stakes--I usually want to read about A and B doing things in their canon-typical setting with their love lives also going on.
However, sometimes I'm in the mood to read about "A is dying, but not of a bullet wound or real-world disease, but of a creepy magical illness, and there's lots of angst and woe." So Hanahaki should be just the thing for me. Except, I usually can't get over the suspension of disbelief required to buy "there's a cure for the disease, but A will lose their memories of B." Heartbreak is sad, yeah, but in most cases not as sad as dying, and it winds up reading like "this character is dying because they're too stubborn to imagine life without someone who doesn't love them back." In the case where, like, A and B are the only two people with knowledge of the villains' super-secret plans, and A forgetting B would also cause them to forget all the time they spent cracking those codes, then maybe I could buy it, but it usually doesn't play out that way.
So, does anyone have any subversions/alternate premises/related tropes that make more sense to them than "traditional" Hanahaki? Or, if you like Hanahaki just as it is, any recs?
This is definitely not me doing research for some original worldbuilding, why would you ask.
