Enjoy!

Chapter 11 [Extra]

What(?)

A sigh went out from the thirteen years old boy.

His eyes locked on the screen, before he tapped a few numbers on the laptop, and watched the reaction patiently.

A groan came out, and he tried another numbers.

Still, it didn't make it.

He tried another and another, desperately, before gave up and lied his back on the sofa.

"Taichi-san, it's really tiring," he whined, gazing at the former goggle-boy that sipped his coffee.

Taichi grinned.

"Come on, if you're really that smart, just put in my password," he sneered.

Koushiro sighed.

"There's no one saying a smart can know what he doesn't know," he groaned, before thinking more.

"It's just 4 words, Koushiro! Just think it clearly!" Taichi then left the place, grabbing more drink for him and his now full of confusion friend.

'Four words. What could it be?' Koushiro had tried to thought every possible answer, and he could only come up with a PIN numbers. That's why he's focusing on number. Desperately, he almost made a list from 0000 to 9999 and checked out what's the most possible, and erased that had already tried.

Taichi was watching him with amused look. Seeing how Koushiro had to deal with computer with such that look, he had to endure the urge to laugh.

"Just 4 words, Koushiro!" he shouted, earning the glare from the boy.

"Then just put in it! You're going to make me crazy!" Koushire yelled out, something that completely out of character.

He calmed down, and began to think again.

But, he couldn't. He reached his mug and drank the tea almost in a second, before sighing.

"Taichi-san, please another hint!" he desperately asked, looking for a hint that could help him earn the answer.

Koushiro himself started to regret accepting Taichi's challenge.

"It's about my new laptop!" Taichi exclaimed.

"So, what's the deal?" Koushiro asked. Because he's free, he did have a little boredom, so playing with Taichi's game-in-law would be an amusing one.

"Just try to make the laptop on its home screen, or desktop…" Taichi rubbed his chin, thinking for a while.

"Whatever of it, just try it," he smirked, and Koushiro nodded.

Really, it's hurting his brain now. Name, birth of date, favourite food or drink, the closest person name, all of them were already tried.

"What did you say, Koushiro?" Taichi yelled from the kitchen, adding more beverages on his arm.

"Another hint, Taichi-san!" the knowledge-boy shouted.

"What?" the former leader yelled back.

"I said, another hint Taichi-san!" the boy started to feel annoyed, to think that Taichi was making fun of him.

"What?!" Taichi changed the tone of his voice.

"Come on, don't make fun of me Taichi-san! I'm tired thinking like hell like this!" Koushiro, faintly opened up his retirement.

"Yes, WHAT?" Taichi, in an equal annoy, yelled back.

Koushiro sighed. Then, a shining bulb appeared.

"What?" he mumbled, and typed W-H-A-T.

When he entered, on the screen, wrote 'Welcome Home!'

Koushiro smirked, really.

"You're really a troll, Taichi-san," he made a mental note, to brought him a pie, and throw it right on his face everytime he asked him to play some weird game again.

A short one, isn't it? I do really like of how Taichi and Koushiro got along, especially when they were searching medicine for Hikari. Even that both of them were completely different, there's no way saying they couldn't get along.

Ah, I'm getting tired write this. Please leave a review, for the kind one out there.

Thanks for reading. See you tomorrow!
