Ciel x Reader - Hanahaki Disease

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.

Your P.O.V.

"How do I tell him? I really love him, more than life itself. Ciel... he's the world to me." You thought to yourself. "I'll tell him today." You decided.

You made him a cup of tea and walked to his study. "I'm just a maid... Would he really love me back?" You shook the thought away and knocked on the door.

"Come in." You heard him say. You smiled at him. "Hello, young master. I've brought you a cup of tea." You set it down on his desk. "My lord, I have something I need to say to you." You hesitated.

"Get on with it." He said, not looking up from his paperwork. "I- I love you." You said. He looked up. "Y/N. I do not have time for you. Honestly, I couldn't care less about what you think of me. Now, get back to work. We don't have time for unnecessary... feelings." He said, continuing his work.

Your eyes welled up with tears, and you ran to your room, weeping. You collapsed, coughing and wheezing. You saw blood and blue flower petals on the floor. "H-hanahaki disease.." You managed to choke out.

Sebastian walked into your room, and saw the blood and petals on the floor. "Miss Y/N, I have to perform the surgery on you. You'll die otherwise." He said, picking you up. "Miss Y/N, there's one important thing I have to tell you. After the surgery, any feelings you had for the young master will be gone." He said.

You nodded. "I know. But, right now, I need to survive."

                      ~ After the surgery ~

Once the surgery was over, you felt... empty. But, you were alive, thankfully. Suddenly, Ciel ran into the room. "Y/N, I'm so sorry! You went through all of this for me. You cared about me when no one else did. I truly love you, I'm sorry I didn't realize it earlier. Y/N, I-" You cut him off. "I'm sorry. Any feelings I had for you are gone." You said blankly.

He took a step backwards. "Y-Y/N..." He rushed out of the room and started coughing. He looked down, and his eyes widened. There were flower petals in front of him, sitting atop a pool of blood.
