A/N: Hi everyone! I've had this idea stuck in my head for a while, so I just had to write it. Lol. Enjoy~!

DISCLAIMER: I do not own Ouran High School Host Club or School Days. I only own (some of) the plot and an OC.

"Fujioka! Hey!"

Haruhi turned around at the sound of her name being called. The rest of the Host Club looked up from what they were doing as well.

"Hey, Amano. What's up?" Haruhi approached her classmate.

"I need help with the assignment. I'm already behind again," her classmate said.

Haruhi rolled her eyes. "I'll help you, but you HAVE to start actually doing the assignments in class, Amano."

Tamaki Suoh, who had simply overheard this conversation, leaned closer to the twins. "Who's she?"

"That's Katsumi Amano," the twins said in unison. "She's pretty talkative but she's really awkward."

"Huh," was his response.

However, days passed, and Tamaki couldn't get the girl off his mind. Days turned to weeks, and soon he found himself infatuated with this girl.

At lunch, he couldn't help but stare at Katsumi Amano. She typically sat alone, but she didn't seem to mind it.

For the first time ever, Tamaki was scared to talk to a girl. However, he managed to keep his secret infatuation just that: a secret.

But not everything can stay secret forever.

It all began during down-time within a Host Club meeting.

"Haruhi!" the twins called.

Haruhi looked up from her homework with an annoyed look in her eye. "What?"

"We're bored."

"And… that's my problem how…?"

"We're gonna look at Tono's phone to see what his wallpaper is," Kaoru whispered.

Haruhi sighed. "Are you trying to see if he's doing that stupid phone charm, too?"

"Yep!" the twins said in unison.

"Have fun," Haruhi said in monotone.

"Aren't you curious to know who it is?" Hikaru asked.

"Not really."

The twins looked at each other and shrugged.

For the past few months, a fad had been going around Ouran Academy: one would make their wallpaper on their phone a picture of their crush; if they made it three weeks without anyone seeing it, the person on the participant's wallpaper would "become theirs".

And the twins wanted to see who was on Tamaki Suoh's wallpaper.

Hikaru got ahold of Tamaki's phone. "You think it's Haruhi?" he asked his twin.

"Only one way to find out-"

"GIVE ME MY PHONE BACK!" Tamaki shouted from across the room. He ran toward them.

But he wasn't quick enough. Tamaki Suoh's secret infatuation was no longer a secret.

"KATSUMI AMANO?!" the twins exclaimed in surprise.

Haruhi looked up, a hint of shock on her face as well.

"GIVE IT!" Tamaki snatched his phone back.

"You like Katsumi Amano?! Since when?!"

"IT'S NONE OF YOUR BUSINESS WHO I LIKE!" Tamaki yelled.

"How long has she been your wallpaper?" Hikaru asked.

"Uh, um… one day…"

"Only one?!"

"It's none of your business!" he repeated. He stuffed his phone in his pocket.

However, Haruhi did not forget that interaction…

It was the next day. Things were quiet that afternoon, but one thing was off.

Haruhi was missing.

"Haruhi appears to be late," Kyoya said.

Of course, Tamaki burst out. "HARUHI'S LATE?! HARUHI'S NEVER LATE!"

"She's been late a few—" the twins began.

"WHAT IF SHE GOT KIDNAPPED?!"

"Senpai, it's fine. I'm right over here." Haruhi had just entered the room, with Katsumi Amano by her side.

Katsumi Amano.

Tamaki blushed immensely and looked away from them.

"Everyone, this is Katsumi Amano. She's in my class," Haruhi announced.

"Hi!" Katsumi said.

Katsumi went around and personally introduced herself to everyone. Then she got to Tamaki. He was still facing away from her.

"Um… hi…?"

Tamaki took a breath. He stood up and took Katsumi's hand and kissed it.

"Pleasure to meet you, Princess~" Tamaki said.

Now Katsumi was blushing. She giggled. "Pleasure's all mine."

A match made in Heaven. Haruhi rolled her eyes at them.

Katsumi was only a few inches taller than Haruhi, but other than that she even looked a little like Tamaki. Her hair was blond, and she wore it down. Her hair reached her lower back. She definitely wasn't unattractive.

Tamaki and Katsumi hit it off, and after Host Club hours, they exchanged phone numbers.

"Call me tonight?" Katsumi asked.

"Of course." Tamaki smiled.

Haruhi rolled her eyes at the two again.

"Haruhi?" Kyoya said. "May I speak with you for a moment?"

She turned to face him. "Hm? Oh, yeah, sure."

Everyone else had already left the room, so it was just the two of them.

"Why did you bring Miss Amano to the club today?" Kyoya asked.

"Tamaki-Senpai has a huge crush on her, so I befriended her and gave them the grounds to meet. Is that so bad?" Haruhi said.

"No, not at all. However, I do want you to take your own feelings into account, too."

"My own… what?"

Kyoya stood up. "I have to get going."

"Uh…"

And then he left.

Take my own feelings into account? What did he mean by that?

Haruhi shrugged and went home.

The following day was a Thursday. Katsumi Amano stood outside the school, shivering.

"Katsumi?"

Katsumi turned around.

"Oh. Hi, Tamaki-Senpai," she said. "Um… it's really cold, isn't it—?"

"I had something I wanted to ask you," Tamaki interjected.

"O-oh. Go on."

"Would you like to do something after school tomorrow?"

She smiled. "Sure! I really liked hanging out with all of you yesterday—"

"No, I mean…" He blushed. "Just the two of us…"

"Just the two…? You mean like a date?"

Tamaki blushed even more. "Y-Yeah."

Katsumi smiled. "Okay."

"R-really?"

"Yeah! I'd love to." She smiled brightly at him.
