"Giotto-niisan! Please don't go!" said a crying 10 year old Tsuna as he clung to the arm of his older brother. His mother stood next to Tsuna with a sad look on her face while watching her youngest son practically beg his older brother to stay while the father loaded the suitcases into the trunk of a cab. His big brother, Giotto, was leaving for a college in America and was going to be gone for a full four years.
"Tsuna…you know I can't stay..." Giotto hugged the crying boy trying hard himself not to let the tears fall. He was going to miss Tsuna like crazy. Not only Tsuna but his mother and father as well. He pulled Tsuna back and kissed the boy's forehead trying his best to comfort him.
"I-I love you, G-Giotto-niisan" said Tsuna while trying to hold back more tears to no avail.
"I love you too, Tsuna. Very much" Giotto hugged his little brother one more time and looked at his mother.
Nana walked up to her son and gave him a tight embrace while silently crying.
"My little boy is all grown up…going off to college…soon you're going to get married and have children…I'm going to miss you so much!" Nana hugged her son tighter as her tears soaked his jacket. Giotto hugged her back while his hand patted her back comfortingly.
"I'm going to miss you too, mom" He said as he kissed her cheek. Iemitsu roughly patted his son's back while giving his famous grin.
"I'm proud of you, son. Make sure to blow them all away in America and show them what the Japanese can do!" exclaimed Iemitsu as he gave a thumbs up and another confident smile. Giotto laughed at his father's happy go lucky attitude. Giotto stood in front of his family one more time giving them all another hug. He ruffled tsuna's hair and gave him another kiss on the forehead.
"Bye, Tsuna. I'll see you when you're all grown up." Giotto gave a sad smile and got into the cab. As the cab drove off, Tsuna ran as fast as he could trying to catch up. As the car sped up Tsuna stopped and cried once again, already missing his beloved big brother.

For an entire year, Tsuna and Giotto would exchange letters to each other. Giotto's letters usually were filled with what he has learned from the Americans such as how they acted and lived. Tsuna was intrigued by the life style of the Americans. On Tsuna's 11th birthday, Giotto sent him a birthday letter which Tsuna decided to read after the party.

After Tsuna's birthday party, he ran upstairs to his room and opened his letter, eager to hear from his beloved Giotto-nii. He smiled as he read the letter.

Dear tsuna
It's your 11th birthday, huh? My little bro's growing up I see. I'm sorry that I can't be there on your special day. Heck, I'm sorry that I can't be there at all. How was your birthday? Did you have a party?
I'm on break from school right now and I'm in Seattle Washington. It's crazy here. So different from Japan. Maybe I'll take you here some day. Anyways, if you look in the envelope, you'll see some pictures I took and something else that I got for you just for your birthday. I hope you like it. I miss you. Tell mom and dad that I love them.
-With Lots of Love, Your Big Brother, Giotto.

Tsuna did as the letter said and looked in the envelope. He pulled out some pictures and looked through each and every one of them. One was of Giotto smiling in front of the Seattle Center Space Needle. Another was of him at his desk studying. Tsuna assumed it was taken by his roommate in secret. The rest were of Giotto and some of his American friends at a beach. Remembering that Giotto had put something else in the envelope, he quickly opened it more and smiled widely at what was there. He pulled out from the envelope a necklace with a really cool brown and white sea shell attached to it. Attached to the necklace as well was a little note that said, "Happy Birthday little bro. Hope you like it". Tsuna wiped a tear away as he smiled at the necklace. He didn't think it was possible, but he somehow missed his brother more than anything else.

Tsuna wrote another letter to Giotto in reply to his birthday letter, thanking him and sending him pictures of the party that Nana took. Days became weeks. Weeks became months and Giotto had not written back to him. Every day after school Tsuna would come home and the first thing he asked to his parents was "Did Giotto-niisan write back?" and every time they would respond with a sad "No..." Tsuna sat on his bed, hugging his pillow wondering if Giotto was ok. What if he got in some sort of accident? What if he had said something to make Giotto mad at him? Tsuna's heard started to hurt as he continued to think of reasons why he hasn't heard from Giotto. Giving up, he turned off the lights, slid under the covers of his bed and silently cried himself to sleep, thinking of his beloved big brother.

A/N: Sorry it was so short, everyone. I'll try to write more in the future. =/
