Hanakaki

Goretober is a yearly challenge, similar to Inktober. It consists in illustrating a series of daily prompts, 31 in total. It takes place in October (hence, the -tober).
This is the tenth prompt, "hanakaki"

"The Hanahaki Disease is an illness born from unrequited love, where the patient’s throat will fill up with flower, they will then proceed to throw, and cough up the petals, (sometimes even the flowers). One of the only ways for the disease to ‘disappear’ is if, the said person returns the feeling (it can’t be resolved with friendship, it has to be genuine feelings of love). The infection can also be removed through surgery, though the feelings disappear along with the petals. If they choose nether options, or the feeling is not returned in time, then the patient’s lungs will fill up with flowers, and will eventually suffocate. "
