Definition:
"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 POV

I lean against one of the walls inside of the Phantomhive manor, arms crossed. In a hallway, to be specific.

As Sebastian flirts with Mey-Rin down the hall, I feel another coughing spree come up. I try to hold it in until I can reach either a bathroom or my bedroom.

I make it to the closest bathroom and lock the door behind me, finally letting it out into the sink. Tears silently stream down my face, past my stoic demeanor.

The flower petals are blood red, like Sebastian's eyes. They kind of blend in with my own blood.

Yeah, I have Hanahaki Disease. And I've been miserable ever since I've gotten it.

It hurts like hell, honestly. The pain in the chest and throat, the struggle to breath as it sometimes results in you passing out...it's hard.

I've fallen in love with a demon butler. He has raven hair and blood red eyes. I bet you've already guessed who he is.

That's right.

Sebastian Michaelis.

He doesn't love me, though. He loves Mey-Rin.

I'm happy for them, but I can't help but to be upset too. I wish I could say that I'm one hundred percent happy for them, but I can't.

As I wash away the blood and petals, an idea comes to mind.

Why don't I just remove the infection by going into surgery? I won't have to suffer anymore, and I could finally be truly happy for the new couple.

They won't ever even have to know of my pain.

I nod to myself, making my decision as I leave the bathroom.

I'm going to get surgery.

Today.

If they have space for me, that is.

I walk into the hospital and make an appointment, to which they immediately rush me to the back to get started. It's a life-threatening disease, so I understand.

I keep a blank face as we walk back, devoid of emotion.

My love for Sebastian broke me.

He never noticed, he was so infatuated with her.

This is why I need this surgery.

For not only my life, but his.

I'm gassed and fall asleep slowly, saying my final goodbyes to my pain. When I wake, I smile through the stinging in my throat. The doctors give me meds for it, and hug me.

Congratulating me on choosing survival.

I smile.

A genuine smile.
