Chapter 4- Rivalry Begins

The door slammed opened. Tsuna and Giotto saw the hitman who was currently leaning on the door frame with his arms crossed. Reborn's forehead had an angry mark and he was filled with anger. He looked and glared at the spiky blonde haired guy from head to toe with great suspicion.

"Who's this alien, Dame-Tsuna?" Reborn asked with a husky and scary tone with a gun in his hand.

'Geez! Bad timing!' Giotto thought.

"Well, I'm G-"

"I'm not talking to you, peasant! Again, who's this alien, Dame-Tsuna? If you don't answer, I'll shoot you all!"

"P-please d-don't, Reborn! H-he is Vongola Giotto, our new classmate," Tsuna responded. His tutor was still in a stormy mood and wanted to kill the guy who was standing in front of him.

"Is that a water gun?" Giotto pointed his finger to the direction of the 'thing' held by Reborn. Tsuna feel so apprehensive about his classmate's behavior. At that question, his tutor pointed his gun at Giotto.

"Do you want me to use this on you?" Tsuna tried to cease Reborn.

"Whowoow! Chillax man... Hahaha! Okay, I'll go now, Tsu-chan. Thanks for your little time. I hope we will do it again. Good day!" Giotto smiled and left.

In spite of all that, the hitman still felt arousing suspicion towards that blonde guy as he had a strange feeling. Tsuna entered when Reborn grabbed his right arm and glared at him.

"What were you two doing a moment ago?"

"Nothing."

Reborn trailed the young boy and pressed him onto the wall. He put his left hand onto the brunet's side. Tsuna gulped when the man leaned closer to him, staring fiercely.

"Don't let me repeat my query, Dame-Tsuna." Reborn stated seriously.

"W-we were just wandering around and had some fun. T-that's all..." The hitman looked deep into his student's eyes and at his lips. By that time, he noticed the flowers from Tsuna's hands. Reborn gripped his fist tightly and let go of the brunet. A momentary glimmer occurred from Tsuna's eyes for a minute.

"Tch, go to your room Dame-Tsuna. I don't want to see you holding those flowers of yours!" Reborn turned his back and shrugged. Tsuna went off towards his room without any circumstances.

~~o Giotto along the street o~~

Even though Giotto was walking along the street alone, he appeared to be so jolly. He sighed and put his hands in his pocket, smiling like crazy.

"Whoa, this day is so wonderful! I'm so lucky that I'd met him but then it turns into a jinx when I saw that old man! It seems that he's protective of my Tsu-chan. Hmph! Nevermind... After all, I can't forget the indefinite period of time that I held his hand! 10 points! Hahahahahahaha! Hahahahaha! Hahahaha-"

Then, he tripped.

"O-ouch! I guess 9 points only..."

~~o Tsuna's room o~~

Tsuna was in a supine position on the bed while facing his cellphone. At the same time, his tutor was passing by his room but quickly stopped. Reborn peeked through the crack created by Tsuna's door. As he saw the brunette text and laugh towards the device he was holding, he grew furious until he couldn't bear it. Reborn burst opened the door. That action made the brunet throw his cellphone onto his bed due to the sudden shock. The hitman walked towards Tsuna with anger.

"Why are you laughing like an idiot towards your stupid cellphone, Dame-Tsuna?!" Reborn madly asked as he snatched the device.

"Give me that! I'm still texting!" Tsuna snarled.

"With whom?!" His eyebrows raised but his student just stayed silent. "Since it's getting late, go to sleep now and don't make any noise. Got it?" Reborn went out of Tsuna's room.

"O-oi! Reborn, how about my cellphone?!" The hitman just ignored the messy brown haired boy and shut the door.

"Augh! Why are you so mean?!" Tsuna pouted.

~~o Reborn's room o~~

Reborn was sitting with his legs crossed on his bed and stared at his student's cellphone, frowning. Recently, the device vibrated, meaning someone texted it. He unlocked the phone and saw the name "Giotto" from the inbox. When he thought that it sounded familiar, he reminisced the moment when Dame-Tsuna introduced the spiky blonde haired guy to him. He opened the message and consequently, his eyes widened. 'What is this idiot texting him?!' he thought and replied it.

[On the cellphone]

Giotto: Tsu-chan, I must admit that you're driving me crazy.

Tsuna: ...

Giotto: Hm? You know what, Tsu-chan? Based on what I had read yesterday, if someone didn't reply with any words, it means that he or she missed you. Well, did you miss me? Did you?

Tsuna: MISS YOURSELF ON THE AIR, IDIOT!

Giotto: Huh? Did you send it to the wrong person?

Tsuna: LITERALLY NO!

Giotto: Tsu-chan, you are very strange tonight... :c

Tsuna: AND WHY?!

Giotto: Because of the way you text. A while ago, you were so calm and didn't use capital letters. Now, you suddenly do...

Tsuna: WHO CARES?! AND STOP TEXTING THIS NUMBER!

Giotto: Eh? Well, I guess you are just tired. Okay! Sleep now, my Tsu-chan. Lets meet in your dreams. Hahahaha! Kidding~ Ja! Ti amo. ^^

[End of conversation]

"What the!" Reborn growled. "And now I know that he's the stupid guy who said 'Ti amo' to my Tsuna! How dense is he?! Damn him!" He gritted his teeth.

~~o At morning o~~

The messy brown haired boy readied himself for school. He walked down the stairs and went towards Reborn who was currently drinking his espresso. Then, his tutor looked at him.

"What do you want, Dame-Tsuna?"

"Where's my cellphone, Reborn? Give it to me please..." Tsuna begged.

"Did you forget that the cellphone you want is from me? I can take it back and don't you steal it or I'll shoot you with the dying will bullets. I will return it in case of emergencies for the reason is that I had observed some nonsensical messages in your inbox. So do not sue me, this is for your own sake."

"For my own sake? What do you mean by that?"

Reborn didn't reply and continued to drink his espresso. Tsuna pouted.

"How cruel!" he whimpered.

"What did you say?"

"I said... 'how cool'... What's wrong with that?"

"Nothing."

"Tsk... What a deaf..." he murmured as he turned to leave. Nevertheless, Reborn heard it.

"I heard that!" He smashed the brunet's head with his green hammer. "Don't play stupidly with me, Dame-Tsuna!"

"Ite, ite, ite! Reborn, it hurts!" Tsuna whined and rubbed his head. His tutor felt guilty all of a sudden of what he did but he didn't show it.

"Go to your school now or you will be late," Reborn commanded, his eyes covered with his fedora.

As Tsuna opened the gate of his house, a black limousine appeared out of nowhere in front of him. The car's window opened and he saw Giotto.

"Yow!" Giotto smiled and winked.

"Giotto-san, why are you here?!"

"To fetch you."

"Eh?"

"Come on, Tsu-chan. Come here to your husband~."

"E-eh?!"

"Just kidding. Hehehehe! Come in, don't be shy."

The spiky blonde haired guy climbed out of the car and opened the other door for Tsuna to enter. Giotto grinned.

~~o Inside the car o~~

Giotto was staring at the brunet. Tsuna was still holding his head as his comrade observed him.

"Tsu-chan, are you not comfortable to sit there? You can sit on my lap for free if you want." Giotto smiled broadly.

"N-no, thanks. My head friggin' hurts," Tsuna replied.

"Why?"

"Because my tutor smashed my head with his green hammer. He also took my cellphone last night. Well, I'm so sorry that I didn't respond you."

'Huh? Meaning to say, that old man was the one who'd texted me last night?! Aah... That's why the text was weird...'

"Oh. He's so mean..."

"You said it, Giotto-san."

"Let me massage your head for a while."

"N-no... I'm okay. Don't worry."

"Is that so..."

~~o Namimori School o~~

As the car came in to the school, Giotto went out first. Then he opened the door on the other side. The girls were cooing but were suddenly quiet when they saw Tsuna come out of the car.

Unfortunately, the head of the disciplinary committee appeared and glared sullenly at Tsuna.

"...You, herbivore." Tsuna 'hiiiiiiiii-ed' and held onto Giotto's shirt.

"Huh? Did he say 'herbibro'?" asked the spiky blonde haired guy, harmlessly. Hibari scowled at him as Tsuna whispered to Giotto's ear that it was "herbivore" not "herbibro."

"… Herbivore, Reborn texted me that you must go home early or he will shoot you." Tsuna sighed in relief, yet he already knew it as usual.

~~o In the classroom o~~

"Class, we will be having a trip this coming Friday," the teacher said. Then the murmurs followed before one of the students asked something.

"To where, ma'am?"

"To the beach." A spreading of murmurs could be heard again. Some of the girls felt so excited while the rest found it boring. In contrary, Giotto chuckled as he imagined Tsuna wearing a bathing suit at the beach.

(Giotto's imagination)

Tsuna was running along the seashore, laughing together with Giotto who was trying to overtake him. They were so happy, but the brunet tripped.

"Giotto-san, help me... I can't stand," Tsuna stated with a plaintive tone.

"Don't worry, my sweetie pie. I'll help you," Giotto said seriously as he carried the cute boy in a bridal style. After a while, they stopped and stared at the beautiful sunset.

"I love you, Tsu-chan..."

"I love you too, Giotto-san..."

They were about to kiss when the teacher called out to Giotto.

(End of imagination)

"Mr. Giotto? Mr. Giotto?"

"M-ma'am?"

"Are you in favor about our trip to the beach?" asked the teacher.

"Oh! Absolutely yes, ma'am." Giotto grinned and looked towards Tsuna.

'Hehehe! I'm so excited," he thought.

TO BE CONTINUED!

Taichi: Oh~! I can't help myself from laughing when I'm writing this chapter. Hahahaha! LOL! Hm~ *deep in thought* I think Giotto has a bad plan, is he? And I'll tell you frankly, Reborn's Leon gun is look like a water gun because of it's color, GREEN. Hahaha! XP Okay! What can you say about this chap? Nice? Boring? Cute? Or funny? Well, flames are also appreciated. Please wait for the next chap. (Chapter 5: Beach Trip) It's gonna be fun! R&R herbibro~ Ciao! ^^
