âIt wasn't fair,â he realized. He realized the world was unjust to him at the ages of four, six, and fourteen. But what about now, when you're standing on the white sink, covered in orange blossoms and scarlet blood?

The Trope Codifier is Naoko Matsuda's 2009 Shoujo manga Hanahaki Otome, or "The Girl Who Spit Up Flowers," about a girl with unrequited emotions who starts spitting up flowers. The symptoms include severe chest pains and flowers emerging from the heart or lungs, followed by vomiting. Kanae is puking and choking on rose petals on the cover of Tokyo Ghoul:re chapter 45. This is two chapters after Eto tortures him with a deceptive Breaking Speech that takes advantage of his unrequited love for Tsukiyama.
Surgery is one method of treating this disorder. The physicians would delicately take the plant from the patient's lungs, quickly healing them. One issue with this procedure is that after it is removed, the patient would lose all emotions for the person they loved, which most people find difficult and difficult to let go of. Another option is for the sufferer to declare their affections for the person they have feelings for and hope that the other person reciprocates. It is thought that these sentiments must be requited in order for the sickness to proceed.

The only way to stop it is for the person they love to be aware, or the infected person to die from the disease.
