It was Gon's birthday and that was causing some problems to Killua. He wasn't used to celebrate birthday. He was only one time at a birthday party, for killing the guests (and then he ate the cake). So Killua didn't know what he should give Gon as a present and every time he asked, Gon just answered :"I don't want anything, except being with you of course."

Because of that, Killua get the craziest idea he ever had.

When Gon woke up on his birthday he looked over to Killua's bed ,on the other side of the hotel room, he became the most surprised boy in the world. Instead of Killua there was a huge gift box, big enough for a human.

Gon read a notice which was laying on the box : "From: Killua To: Gon"

Gon opened it and fell down on the floor because the gift inside the box was a really big surprise. It was Killua, embarrassed and tied up with gift ribbon.

"Killua …" Gon began, "I need a explanation."

Killua blushed: "Well you said you don't want anything except being with me. So I decided to ..."

Gon interrupted him: "You are my present? That would mean you're mine."

Killua blushed even harder: "Idiot! Don't say something like that. I know it is a stupid idea but when I realized it I already tied myself up."

"What? How did you do that?" Gon asked in surprise.
"Don't ask!" Killua answered sweat dropping.

Gon took Killua out of the box and hugged him. "That is the best present I ever received."

…

…

…

"You won't untie me, right?" Killua asked.

"No! You are mine now!" Gon answered.

Somehow Killua didn't regret his idea.
