Here we go again.

I was hiding again.

Who am I hiding from?

Her...

You don't know who I mean?

Her name's Sonoda Umi. She's been my very best friend ever since kindergarten. We did everything together. Nothing could seperate us! We always tried to stay together, so nothing could rip us apart.

When we started middle school, she started to act in a... rather weird way. She was practically 'obsessed' with me. There wasn't a single second she wouldn't be around me. She'd always look at me with that sweet smile, but as soon as someone gets close to me, that smile fades into an empty and... I don't know... scary? expression.

Her eyes look empty when I talk to others. As if she'd freak out any second.

Well, that's not the weirdest part about it. She'd always follow me around and tries to collect things I used. Once, I threw away the rest of an apple and I saw her picking it up and putting it into her back. She then puts that innocent smile on and follows me again.

But this time, she completely freaked out.

That's why I'm hiding.

I wanted to confess to someone today. Another classmate we have. But as soon as I stood on the rooftop with that certain person, Umi came around the corner, holding a knife. She was crying, and her face was full of anger.

"How... Dare you!" She screamed and tried attacking the other student with the knife. I quickly took them by the hand and tried to escape.

Well, what a bad idea it was to walk that way. As soon as we wanted to run down the staircase, Umi was already waiting for us. She threw the student on the ground. "She's mine! Why'd you try to destroy our relationship?!" She stabbed the knife into the visibly shocked one underneath her.

The school was empty at this point, since classes had already ended a long time ago. I couldn't get someone to help.

I stood there and couldn't move. I didn't realize what just happened. Suddenly, Umi began to laugh like crazy. That's completely different from her usual self. Blood was making it's way to my feet. That crazy laughter was the moment my brain woke up. I ran away as fast as I could, a few tears were forming in my eyes.

I felt Umi's presence right behind me all the time.

Don't get me wrong. The one I wanted to confess to... Well, I'm not sure if I really loved them. I just wanted to know what it feels like and... maybe Umi was still the only one causing my feelings to go up and down. Like in a rollercoaster.

I wasn't sure. I just didn't want it to be real. I knew Umi would love a confession like that from me, but how can I be together with someone as crazy as her? But still, I couldn't deny my feeling for her.

I hid behind a large garbage bin. But it was useless. I heard Umi's footsteps approaching me after a shirt while.

But something was wrong.

She was coughing, gasping for air. I heard a loud thud. Did she fall? I peeked around the corner.

She was lying on the floor, various flowers and flower petals were scattered all over the floor. She tried to get up on her knees. Her back was facing me. She was coughing badly and held her hand in front of her mouth.

She turned a little and I saw, how all those flowers were coughed up by her.

This can't be real... you're kidding right? Coughing up flowers... hahaha...

Well, at least it's what I thought.

I know it may sound weird to do that in such a situation, but I quickly got out my phone to search that up.

And what I found confused me.

Hanahaki Disease is a disease in which the victim coughs up flower petals when they suffer from one-sided love. It ends when the beloved returns their feelings (romantic love only; strong friendship is not enough), or when the victim dies. It can be cured through surgical removal, but when the infection is removed, the victim's romantic feelings for their love also disappear.

But...

No...

I love her!

Yes! I know she's crazy but...

She has a sweet side as well...

Maybe I can change her!

"Umi!" I quickly got out of my hiding spot and came to hug her. She wouldn't Stop coughing. She looked like she was going to faint due to the fact that she wasn't able to breathe properly. "Stop! It's no unreturned love! I love you, Umi!" Tears formed into my eyes again and I tightened my grip around her.

"Please..." I shook her body a little since she wasn't responding.

She was laying in my arms and didn't move. "Umi!" I cried out. I couldn't help but just kiss her. I wanted it to be cliché. I believed she'd wake up from it. But she didn't.

I cried, screamed. But no one heard if. A tear of mine fell onto her face. I hugged her tightly again. But this time, her arm were wrapped around me. "I... love you too." She weakly responded.

"Umi..." a faint smile came across my face while more tears ran down my cheeks. But this time they were tears of joy. Tears of happiness. I couldn't be more happy.

I got my dearest friend....

No.

My lover...

I got her back.

And I couldn't be happier.

"I'll change... If it's for you..." She gave me a gentle smile.
