Len needed some time to think. And so his father agreed to let him stay home instead of going to school that day.

Does he even need to go to school?

Len was…frustrated, disappointed at himself. He failed at catching 'Lily', he failed at controlling his own mind, he has utterly failed himself.

The whole time, the whole process, the teams were trying their best (although without using their brains) to catch 'Lily' and all Len did was stare at her face when he saw her.

He was just… staring at her. He couldn't help but think how…beautiful she was, behind that mask, those bright blue eyes he saw, her hair's like an Empress' silk shining under the moon, and that fair skin of her was just…

Len stopped himself.

Deep breath, deep breath, Len, he thought, keep calm and steady…peace.

Think about the riddle…

After the three Atlantis sank, Pandora would be taken.
To the Sun and the Moon, where the cursed Flora stays hidden.
The scent of it brings delusion and illusion,
Let Janus guide you, to conclusion or confusion.

It didn't make any sense at first, but after the whole process, after it happened, it all came together. Like a 10000-pieces puzzle that Len had tried to play before, if you've never even seen the original picture, it'll definitely be harder, or else, impossible to know where to put the pieces.

The three Atlantis: Atlantis never existed. It all started because of the myths, and then it became stories, then movies. It's all in our minds, our imaginations. And that was it. She toyed with his mind three times. First was his fear of not knowing things, although how 'Lily' knew that would stay a mystery. Second, was the riddle itself. Then it was 'Lily' herself. This is a possible explanation to Len's situation…

Pandora: Of course, the diamond.

The Sun and The Moon: She said that she 'stays hidden' there, telling us that she will come from the sky. And also adding the Korean folk tale, she escapes to the sky.

The scent of it brings delusion and illusions, Let Janus guide you, to conclusion or confusion: The scent was the 'smoke bomb', at least that was what Len thinks it is. The 'delusion' wes the roads, one with the lily, the other without it. And the 'illusion' was the air vent. And 'Janus' were the teams that headed the wrong way. They were guiding him to the wrong way, the 'confusion', and the other way was the 'conclusion', the way 'Lily' headed.

But then, something didn't make sense, cursed flora. The flora would signify 'Lily' herself, but, why cursed? It's like she's telling him something.

And…why is it like 'Lily' made the riddle…for him? It was as if 'Lily' knew him.

This was only making Len even confused.

Maybe I should have some coffee…or tea, tea is better, and a book to spend the afternoon, yes, nice and easy. You're okay, Len, you're o—

"Len! You have a visitor!"

And there goes his peace and his nice afternoon. Ruined by his father and this visitor.

Len wanted to just rush out there, tell the visitor to just go away, slam the door shut, and start playing his violin as loud as he can so he can't hear any other things.

But being the high IQ, well-mannered boy is, he walks out of his room and down the stairs slowly so no one will see how annoyed he is.

And then everything stopped.

Len spitted out a word in French and almost ran away. He was wearing a plain white shirt and random shorts he found somewhere in his drawer. He never thought a human being would take the time to visit him, and he never even had the slightest thought that a girl would visit him.

So what the hell is Rin doing here?

And what the hell is he wearing? How could he show himself wearing…this in front of a girl?

And school only started just an hour ago, why is she here? Why isn't she at school?

"Hi, Len," Rin casually greeted him.

Len asked, "Why aren't you at school?"

"Because you weren't there, and I probably know everything the teacher is trying to teach us. So, I'm bored. And we have some personal matters to talk about." Rin said.

"Personal matters?" Len's father asked, "Len, what've you done to her? Wait, you've finally hit puberty?"

"FATHER." Len shouted, "I did not do anything to her. And what does this have to do with me hitting puberty?"

All Len could focus on was Rin's giggles.

"I'm sorry for the misunderstanding, mister," Rin told Len's Father, "I'm just going to ask him about a project that we're doing in school."

"Take your time; we've got some cake here, chocolate or cheese?" Leon asked Rin.

"Cheese, thank you." Rin smiled.

"Such a nice girl," Leon smiled back, "Why can't you be more like her, Len?"

"I want green tea, thank you." Len said.

"…You're welcome." Leon forced a smile.

"Now, can you wait in the living room? I need to change my clothes." Len told Rin.

"Like I said, it's a personal matter; I want to talk about it in your room." Rin smiled.

"Well…sure." Len shrugged.

Len's room was on the second floor, the small room at the end of the corridor. There's not much in his room, a cabinet, a bed, a desk and a computer. And there's a shelf with at least 217 books inside. Leon didn't know how Len got the money to buy all this, but he'd rather not ask.

"Nice room you have." Rin started looking around, paying attention to everything in front of her eyes.

But she didn't do that when she walked into his house. She was only paying attention to this particular room. Len knew something was wrong.

"Now, about our personal matters." Rin smiled.

And Len was right.

Len just had enough time to turn back and block a kick from Rin that was about to hit his back. But Rin used a lot of her strength, causing Len to fall backwards.

"The next time I ask you what the riddle is about, don't lie to me." Rin stared at his eyes.

So, she found out about the riddle.

"I could've helped you." Rin sighed.

"Help me?" Len asked. "Wait…how did you…"

"They tried to get the police to keep it a secret from the people. But something like this won't be a secret for too long. And guess what, you're the star of the whole case."

"The star?"

"They've even give you a code name, to protect your privacy and information."

"Oh," That got Len's attention, "What is it?"

"Crack." Rin said.

"Crack?" Len smiled, "As in software cracking or as in cocaine?"

"Of course, in software cracking." Rin smiled back, "But, let us get back to our original topic."

Len gulped for the first time in five years. (The last time being when he was experimenting with chemicals, he accidentally causes a minor explosion that ruined his mother's cars and felt the wraith of her.)

"Why did you not tell me about the riddle?" Rin glared at him hard, "We could've caught her. Yes, I know you are a genius, but only one having one genius won't help you. Do you understand what I'm saying?"

"Yes, I do." Len took a deep breath, "But please, do let me explain my situation. I have worked with the police before, a couple of times actually, and so I have more experience on these cases. Second, even if I want to tell you about it (Which he actually wanted to before), I can't. This kind of information isn't something everybody could know about. Even if something slightly goes wrong, our chance of catching her would decrease, greatly. And may I ask why you are so eager and anxious in catching her?"

"Because I want the things she's stolen to be back in the museum. Think about it, Len, all those works and paintings, especially Leonardo's original notes. I admire creators, and just thinking of these remarkable works, stolen, makes me boil in anger." Rin realized she was a bit agitated, calming herself down, she softly spoke the word, "Sorry."

"I understand, Rin." Len sighed, "All those works, those paintings. The history and stories behind them, the wisdom and knowledge. I understand."

"You do?" Rin looked at him strangely, "Most people don't."

"But am I 'most people'?" Len grinned.

"You arrogant bastard." Rin giggled quietly. Then Rin looked up towards Len's desk, "I notice you have a Chinese chess set."

"Well, yes," Len answered her; "Do you know how to play it?"

"Of course I do," Rin replied, "Do you want to go for a round?"

"Sure," Len said back almost immediately.

Len opened the chess set, touching the flat circular pieces as he set them up and think about the rules.

Two cannon, two advisor, two chariot, five soldiers, two elephants, two horses and of course, the general. On the board, a river and the palace.

Cannons can jump over other pieces to kill.

Advisors move diagonally in the palace.

Chariots, almost like the rook, move straight, considered the strongest piece.

Soldiers move one step a time, not the weakest, considering the fact that it is the only piece that the general cannot kill.

The elephants move like a large 'L', or according to the Chinese way, the word '田' while the horses move just like the knight or the word '日'.

The general, of course, like the king.

So much fun rules for the game. Just naming a few isn't enough.

For example, when the way is clear for the enemy's general, it can directly fly across the board to kill another's general. The elephants cannot cross the river. The soldier cannot be killed by the general.

Len likes the Chinese chess better than the common chess. So much rules, so many ways to kill and people can often kill you without yourself realizing.

One round turned into ten rounds, with all of them lasting about 40 minutes long.

It was the most fun Len had in years.

Kaito stared at the two empty seats; both Rin and Len didn't come to school, what a coincidence.

He was quite…disgusted by himself, playing dumb was required to get near to Len, at least let Len think that Kaito isn't as smart as he looks. But he could still see that doubt in Len's eyes, that suspicion. Well, Len is the cleverest guy in this place for a reason.

Both Rin and Len are good, both of their brains and skills are a must.

He'll continue this act for a while, at least until the time comes.

Now then, the riddle, Kaito thought, surely Len had solved it already. Kaito might need both of their help if he wants to get that 'Lily', and of course, the treasures.

Just how much he could get if he sold those in the black market?

And he had already received some information from Japan, just two minutes ago.

Another riddle has arrived.

And Len is definitely going to need help with this one.
