Oh my god, I just rewatched the first Sekai-ichi OVA and just….KYAAA! I suffered a major nosebleed! Especially the scene in the library when they're alone, hugging and kissing, the curtains billowing around them, Ritsu basically confesses again, it's all just so cute! Kawaii ne~! Ritsu is just so CUTE!

Okay, sorry, sorry. I went total fangirl….let's just go to Chapter 5….Ritsu's (and Riko's) birthday! Hooray! What does Riko have in store? :3

Sorry for the super long Author's Note!

Enjoy~!

-Chapter 5-

*One Week Later*

Onodera awoke to the feeling of something on his feet. He looked down to see a reddish-brown ball of smooth fur. Momo was curled up, sleeping peacefully at the foot of the bed. Her floppy ears twitched occasionally and Onodera smiled. He felt another weight on him and remembered Takano slept over. Turning and trying not to disturb both sleeping figures, he looked at his bedside clock. It's face glowed a red 9:30 a.m.

Turning back around, he nuzzled into Takano's broad chest. In total bliss, he drifted back to sleep for another half hour. This time, he woke up to Takano kissing him.

"M-Masamune, what're you doing?" Onodera yawned cutely and Takano kissed him again.

"You're cute when you sleep," Takano simply stated and pulled him closer.

"We have to get up."

"Hmm…no."

"It's ten in the morning! I feel lazy sleeping in so late," Onodera whined as he wriggled, trying to get out of Takano's arms.

"It's Saturday, who cares? Oh, by the way….Happy Birthday."

"Eh?" Onodera looked back at the alarm clock that also displayed the date. Sure enough, it was the 27th of March.

"Don't tell me you forgot?" Takano chuckled.

"I got to call Riko! First, I'm going to take a shower."

"Can I come with you?"

"W-what? No! P-Pervert!" Ritsu scrambled out of bed and into the bathroom. Takano was about to follow him anyways when his phone suddenly rung. He grumbled and grabbed it, flipping it open.

"Hello?"

"Ohayō Takano-san! Do you know what today is?" Riko called on the other end. She sounded happier than she would be in the morning.

"The 27th of March: you and Ritsu's birthday," He said matter-of-factly, as if it was the simplest question in the world.

"Precisely. I have a plan and I need you to play a part. Take Ritsu out and come back around one. Okay?"

"Since when did you become leader?" Takano scratched Momo's back as she woke up.

"If you want an exciting evening, I suggest you listen," Riko said seriously. Takano froze and narrowed his eyes.

"Don't tell Ritsu anything, just take him out to lunch then go shopping or something. Do whatever gay couples do," Takano heard her suppress a squeal and he smiled slightly.

"Fine. This better be worth it," Takano sighed. Riko laughed, a bit evilly, and sang, "Oh don't worry. It will!"

She hung up and Takano rolled his eyes. Ritsu came in just then, drying his hair. Momo stretched then yawned, causing Onodera to smile at her cuteness. He ran his hand down her back and up again to pat her head. Takano rose from the bed and headed towards the bathroom. Momo automatically jumped down from the bed, following Takano the whole way. She had grown strangely attached to Takano and followed him everywhere. Whenever he left, Onodera noticed she grew progressively sadder. As soon as he came back, she would run around like a little kid.

Takano shut the door and Momo plopped down in front of it, waiting. Onodera dressed then called Riko to wish her a Happy Birthday. Ten minutes later, Takano came out-with Momo close behind-and announced, "Let's go out."

"Eh?"

"For your birthday, I want to take you out. Let's go," Masamune practically dragged him out of the apartment.

"That was delicious, thank you," Onodera commented. They were just leaving the restaurant where they ate lunch. Takano had treated him and now they were just walking around. Takano still had half an hour to kill until he had to bring Ritsu back, to Riko's instructions. He spotted a bookstore nearby and grabbed Onodera's hand, leading him to it.

Onodera looked around, eyeing all the books like he was a kid at a toy store. He picked up Usami Akihiko's latest book and sighed.

"I remember when I worked on his books. They were always so good, I'm sure this one is too," He flipped through the pages, admiring the work. He sighed and put it back down, "too bad I'm broke."

Onodera mumbled the last part, not intending for Takano to hear. He secretly bought the book when said male wasn't looking. He checked the time and noticed they had to back in twenty minutes. As they walked to the train station, the older male entwined his fingers with the younger ones. Said male blushed but didn't say anything. Takano saw the smallest trace of a smile play on his lips.

Reaching Onodera's door, Takano got a text.

To: Takano Masamune

From: Onodera Riko

Leave for ten minutes. Go wrap a present or something; it's a surprise.

Takano frowned but made the excuse he left something in his apartment anyways. He told Ritsu to go in anyways and the younger one complied. Onodera walked in and noticed a soft light flickering from the dining room. Frowning, he walked in to see a big cake on the table.

The cake had fluffy white frosting and one lit candle in the middle. The candle displayed a big, red '27' and as he walked closer, he saw there was blue writing around the 27. In very precise cursive, it read, "Happy Birthday Nii-san!"

Riko emerged from the kitchen and yelled, "Happy Birthday!" She leaped on Onodera, embracing him tightly.

"R-Riko! How did you get in here?"

"You have a key underneath the door mat," Riko giggled and exclaimed, "That's not important anyways. Happy Birthday to us, twin! I baked this cake myself."

Riko had always been an excellent cook and baker. Onodera mouth watered at the thought of her food.

"It's your favorite; red velvet with lots of cream cheese frosting!"

"Really? Thank you Riko," Onodera blushed slightly in embarrassment. Riko had put so much effort and thought into today and he had forgotten the importance of it. He reddened even more, ashamed he hadn't even gotten her a present.

"I-I'm really sorry, Riko. I totally forgot it was our birthday today and I didn't think to get you a present."

"It's okay Nii-san. I hate presents anyways. Oh, thanks for reminding me! I got you a present," She waltzed into the living room, coming back with a square-shaped package, wrapped in red.

"You didn't have to Riko! The cake was enough," Onodera shook his head.

"Shut up Ritsu, just take it," She thrust the present in his hands and grinned. He opened it carefully and he softly smiled. It was a photo album. It had a soft brown cover and on the front was a picture of them entering middle school. In the picture Onodera was stiff, with a red face and a nervous smile. He looked like the cute 'Oda' Ritsu he used to be. On the other hand, Riko was hanging off his shoulders and had a huge, confident grin. She was making a peace sign with her hand and a big white bow was clipped in her hair.

As he flipped through, his smile grew bigger. They were all pictures of him and Riko, from childhood all the way to college. On the last page was a picture of them at an airport, heading off to England. Onodera wasn't really smiling in this picture and he remembered it was after his breakup with Saga-sempai. Riko had looped their arms together and had a small smile. Ritsu noticed that there was writing below the picture and it read:

'You always acted like a big brother for me and I couldn't ask for a better twin. Thank you Nii-san for always being there for me and taking care of me. Now it's my turn.'

Onodera's eyes clouded with tears and he suddenly hugged Riko. She encircled her arms around his waist and repeated the last written words, "Now it's my turn."

They stayed like that for a few moments, until they felt Momo rub against their legs. They separated-both sniffling slightly-and Riko crouched down to rub Momo's belly.

"So, do you like it here Momo-chan?" The little dog's tail thumped against the ground and her eyes twinkled.

"Ah, I have one more thing for you Ritsu. But close your eyes!" Riko ran into the living room. Onodera chuckled and closed his eyes. He heard her footsteps come back and rustling. He felt her touch his head then she pulled back.

"You can open them now."

He peeled his eyes open to see her beaming and emerald eyes shining. He looked around but didn't see anything. He had a puzzled look and asked, "What did you do?"

Riko opened her mouth to answer but they heard the door open and Takano walk in. He stopped short and stared at Onodera, his mouth slightly agape. Onodera grew even more puzzled but Riko quickly grabbed her stuff.

"Okayyoutwohavefuncallmebackwhenyourdonebye!" Riko ran out the door.

Takano continued to stare, much to Onodera's annoyance. "Why are you staring?" He grumbled. Takano smirked suddenly and the younger one saw the evil glint in his eyes.

"It's your birthday Ritsu, but I appreciate the gesture," He took a step forward but Onodera stepped back.

"W-what are you talking about?" Ritsu sweat dropped.

"My little Ritsu-Neko," Takano's smirk grew. The brunette blinked then blushed.

"N-Neko? Wait, what?!" He ran to the bathroom and looked in the mirror. Takano heard him gasp. On top of his head were light brown cat ears, blending into his hair perfectly. He actually looked like he grew Neko ears!

"No, i-its not w-what y-you think! R-Riko did this! She put t-these on my h-head!" Onodera waved his arms frantically and flushed bright red.

"I think your sister is my new best friend," Takano proceeded to pounce on Onodera.

Unknown to them, Riko was on the other side of the front door, her ear pressed to it. She was trying to desperately hold back squeals as her nose gushed red liquid.

Okay, I had to end it on a hinted lemon XD This was the longest chapter so far, I think. How did you like it? Riko is my favorite character X3 Bwhahahahahaha!

Aww, brother-sister moment! I had to add that because I thought it would be totally sweet and appropriate for the story. It might be a couple days until the next chapter because I need to think of how to lead up to the next part I want to write.

Well, see you next chapter! :)

(Remember, any idea for this story, please share!)
