The Hanahaki Disease is an illness born from one-sided love, where the patient throws up and coughs up flower petals when they suffer from one-sided love. The infection can be removed through surgery, but the feelings disappear along with the petals

Amy~sama hadn't been feeling well..not since she'd fallen in love with her best friend and learned he liked Kawaii~chan. Amy~sama had begun to cough up petals and blood...each day it got worse. It was easy to tell something was wrong with her when she'd run off to cough.

This is Amy~sama's flower

The same thing can be happening to OC or they could be the first to figure it out

(I'm bored and making a whole bunch of new scenarios)
