So was at my friend's birthday party and she introduces me to a fanfic where the OC has a crush on Todoroki but Todoroki loves Momo instead (man I ship them so much) and she develops hanahaki which is basically a disease where person coughs up flowers when they experience a one sided love and I thought, why not do it with Oikawa?

I know a lot of people call him a piece of trash but I feel like he's just misunderstood (I know he treats Kageyama like shit but honestly, teenage jealousy can be rough).

Hope you enjoy this. It should go on for about 10 chapters or maybe less but we'll see.

I don't own the characters (except for the OC Rin Tachibana).

Hanahaki.

A disease that ravages the body when one falls into a one-sided love relationship, making the person cough up flower petals as it spreads through the lungs.

The only way a person can be cured is either by making sure the other person falls in love with them as well or they can opt for a surgery to remove the infection but at the price of losing the love they have felt for the person they loved but never had any feelings returned to them.

Never would I have thought this stupid disease would happen because I fell in love with a certain piece of trash.

The more I watched Oikawa smashed the ball across the court, the more I felt like I wanted to smack him across the face.

The smirk on his face, the cocky way he stood as he waves at his fangirls, the way he teased his teammates, lacking the respect they deserved so much for having to put up with a person like him.

So when did it all start?

I stood in front of the mirror, blood splattering the sink as I tried to hack up whatever was in my throat. The first time I had coughed up flowers made me wonder if I was hallucinating or if it was all just a stupid trick. Then again, I don't think that it would be possible for someone to make a practical joke of putting flowers in my food and let me hack them up.

I wiped my mouth, my throat starting to get sore as guzzled some water before heading back to class. This problem was driving me up the wall not only from the fact I had to hide the fact that I was in a one-sided relationship crisis but also due to the fact that the person I'm infatuated with is the single most annoying popular guy on campus.

Tough luck I had to fall in love with a jerk like him.

I sidled into the classroom, holding a handkerchief to my mouth as I plopped down on my seat and opened a book to pretend to read it. He should be appearing in 3, 2, 1…

"Kyahh, Oikawa-san!" the girls squealed as the ever all so mighty Grand King of the Court (a nickname I had heard from my cousin Tobio from Karasuno) as they flocked over him.

I could never forgive the fact that he had treated and is still treating my little cousin so cruelly over something as stupid as being better at him in volleyball.

Even more, reason I wondered why the hell I had to have been landed into this shit.

"Iwai-chan! Ohayo!" he grinned as he waved to his best friend who was in the class next door. Some of the girls squealed as he gave him a nod before ducking into the class, the bell rings to signal the start of the lesson as everyone headed to their seats.

"Morning, Rin-chan," Oikawa grinned as some of the girls hissed at me, some of them giving me looks that suggested I should be careful of some of my things going missing later in the day as the teacher came in.

The only reason Oikawa would ever speak to me was that he was the volleyball captain and I was the manager of the men's volleyball team.

Every day I had to watch him and the others play on the court, the ball whooshing from one side to the other as they fought, a battle of wits and strength on the court. Yells and screams as they passed the ball from one to another, attack after attack as blockers rose to meet them.

The thrill of the game made my heart race even though I never played it.

One of the main reasons I joined the team as manager was that they were in desperate need and for some reason, they had roped me in. If Oikawa knew that I and Tobio were cousins…

No, now wasn't the time to bring Tobio into the mix. He has much worse problems to deal with now. Like kicking Oikawa's ass on the court.

As much as they're my team and I love them to bits, seeing the smirk getting wiped off his face would be the best thing that ever happened to me. And for his sake, if he ever wanted to be a normal human being.

"Neh neh, I wonder why Oikawa-san always talks to Tachibana-san."

"Ah she's the manager, isn't she? Gah, I wished I had signed up as manager but I don't know anything about volleyball."

"I heard that her cousin is that genius setter from.., Karasuno was it? Oh, I've seen pictures of him in a magazine and he's super cute!"

I smirked to myself as I stuffed my books into my bag and stood up to go for volleyball practice, knowing full well that Oikawa hated it whenever someone brought up Tobio in a conversation and that those girls never stood a chance in getting Oikawa's attention.

The guy only lived and breathed volleyball after all. I was surprised he hadn't had a girlfriend given how popular he was.

"Yo, Rin," Iwaizumi called as he stood at the door, a smug look on his face as he waited for me to come and walk to the gym together. For some reason, Oikawa was missing in action today from the class which I thought was pretty odd since he would normally wait for Iwaizumi but this round, he had upped and left the moment the bell had rung.

"So today we'll be going through the drills and practicing blocks and serves. Ah, Yahaba-san might be put in as a spare setter this round but we'll also let him play on the court…" I murmured as we walked down the stairs into the outside world, the wind hitting my face along with the slight breeze.

We turned to walk to where the gym was when I heard a familiar voice said, "Sure."

My heart leaped in my chest as I heard the familiar voice said those words, words that normally wouldn't mean squat to me but for some reason, my heart was racing so much.

What was this feeling?

Was it… jealousy?

"Ah, but I have to go to volleyball practice. What about we meet after 5 pm tomorrow for coffee in town?"

"Haik! Thanks so much, Oikawa-san!" a girl squeaked, although I didn't recognize her voice as I felt something constricting in my throat, my chest starting to hurt as I clung onto the wall for balance.

"Oi, Rin! What's wrong?" Iwaizumi demanded just as I blacked out, the last thing I saw was pink floating in the sky as I fell into Iwaizumi's arms.

"Seriously? I didn't know that damn thing was a thing."

"I'm afraid it is, Iwaizumi-san. Well, she can always go for surgery to remove the infection but she will forget about the person in the end. Poor child, youth can be such a painful thing," a woman's voice said as I cracked open my eyes to see Iwaizumi sitting next to my bed.

"I'll leave you to it," the nurse said as she popped out of the office to leave the both of us in awkward silence when Iwaizumi finally said, "She said you had hanahaki."

That just confirmed my worse fears. A thing of fiction, something I thought would only happen in shojo manga was now happening to me and if I don't do anything about it, I either bring my love to the grave and cough up flowers for life or I can just get the damn thing out and forget I even loved Oikawa in the first place.

"Shit it all. Why him of all people?" I groaned as I hacked up a single petal. It was a sakura petal, pink and smooth despite it having been hacked out of my throat as it fell to the floor.

To think I had to faint in front of his best friend as well…

"Rin, how about you try and be my girlfriend?"

My heart stopped as I turned to look at Iwaizumi, who was slightly flushed in the face as he breathed in, "I know you like Oikawa but now that he has a girlfriend, it would only hurt you even more if you continue to have any feelings for me so I was hoping that if you were with me, perhaps it might help relieve the disease."

Iwaizumi Hajime. One of the smartest and hottest boys in our year whom I see as a potential opponent in arm wrestling and squabbles is asking me to be his girlfriend.

But then, I didn't love him the way I did Oikawa, although Iwaizumi was one of the few people I cared most.

But I had to stop this stupid hanabaki disease or it's just going to make things more complicated.

"I'll ask this again; will you be my girlfriend?"

Silently I nodded and Iwaizumi looked like a lot of pressure had been lifted from his shoulders as a small smile formed on his face, reaching out to put his hand over mine just as when the nurse came in, her cheeks flushed with excitement as she congratulated us on becoming a couple. Apparently, she had been eavesdropping outside.

"Come on, we better get to practice or Oikawa will have a row with us," Iwaizumi murmured as he pulled me to my feet, guiding me out of the infirmary.

This would be the start of a web of lies that would only break more than just one heart.

Well Iwaizumi has always been one of my favourites as well so thought it would be cool to have a love triangle of sorts hehe.
