A/N: Wow, Chapter 5 already, hard to believe! Ok, a quick note to anyone who reads my other stories. Complete Chaos will be having a break from being updated.

Purple-dragon-123 – Mokuba's not THAT evil. Though he is more extreme than in the anime.

Disclaimer: We don't own Yu-gi-oh, or Playstation 2. But we do own Seven Seas Down. If that counts for anything.

Forbidden Temptations

Secrets

Serenity and Mokuba were on level 10 of Seven Seas Down, which meant they had to solve a challenging math problem to unlock the next level. Mokuba didn't get it, as he usually avoided this game because he had to actually think to beat the level.

"I don't get it!" Mokuba whined, throwing the controller at the screen displaying the evil math problem.

"Look, if you do it this way… " Serenity bent over Mokuba to show him the proper method of figuring it out.

Just at that moment, the door handle turned and a steaming Kaiba stormed in.

"What are you - " He started to yell, but then he noticed Serenity, who was sitting next to Mokuba in a position that suggested they were kissing.

"What the hell?" Kaiba yelled, now louder. "Are you two - " He stopped, at a loss for words, a rare moment for Seto Kaiba.

Serenity turned around, blushing at his assumption.

"Absolutely not." She said.

"Oh, well then." Kaiba said, still not sure. He looked around the room, collecting himself.

"What the hell is she doing here anyway?" Kaiba said pointing an accusing finger at Serenity.

She looked at his finger, then at Mokuba.

"I'm his tutor of course." She said, wondering why Mokuba hadn't informed his brother about her. Maybe he didn't want to admit he needed help, though his grades sure reflected that he did.

Mokuba slapped his hand on his forehead, wishing she hadn't said what she just did. He really didn't want to know what his brother would have to say about this new information.

Kaiba looked at the two of them. "Right. Nice little excuse." He said. "No really, I want to know what she's doing in my house!" He said, raising his voice to a yell once again at the last few words.

Mokuba turned his face. Maybe there was hope yet to get out of this. But Serenity was too quick for him.

"It's true." She said, uneasy. "Didn't Mokuba tell you?" she looked at Mokuba, who refused to meet her eyes.

Kaiba now shifted his glance from Serenity to Mokuba. "No…" he said turning his head. He was about to say something more when his cell phone started ringing loudly. He glared at both of the accused, and said, "I'll be back." And proceeded to answer his phone. "Hello, Kaiba here." He said in an exasperated voice, before walking out the door with a slam.

Serenity and Mokuba sat in an awkward silence for a moment, and then Serenity turned to look at her pupil.

"Why didn't you TELL him I was your tutor?" Serenity started, trying not to get too angry. She had just been embarrassed and yelled at by Seto Kaiba. That didn't make her too happy. Who was HE to accuse her of anything anyway? She shook her head, as if to stop thinking about the incident.

"I didn't want him to know I needed help." Mokuba whined.

"Quit whining." Serenity said. "Did you think he was never going to find out?" She looked reproachfully at him.

"Um…" Mokuba said, with an embarrassed look.

"Anyway…" Serenity said. "As long as he's occupied," she said, stressing the last word, "Why don't we continue with our studying?"

Mokuba groaned. "I'm sick!!" he protested. "And hungry…" he said.

Serenity sighed. "Fine. I see we aren't going to get anywhere today…so I'll be back tomorrow. I'm not going to let you fall behind on your work!" She said, gathering up her bag.

Mokuba glared. "Fine." He said, turning back to his Playstation 2.

Serenity clenched her hands, her nails digging into her hands. He really was a royal pain.

"See you tomorrow, same time." Serenity said, walking out.

"Don't let the door hit you on the - " Mokuba's comment was cut off as Serenity closed the door.

She muttered to herself as she tried to find her way to the door, in their huge mansion. "I think I remember this portrait thingy. The one with the glaring eyes. Oh wait! They all have glaring eyes! This is the Kaiba mansion, idiot!" she continued talking to herself as she walked down the long corridors. Every now and then, she thought her surroundings looked familiar, but she was wrong. Did Kaiba think it was funny to design his house to make people get lost? That could be his idea of a joke.

Serenity was not the type of person to panic in dire situations, so she just calmly tried to retrace her steps to Mokuba's room, and ask him to take her to the door. It would be embarrassing, but at least she wouldn't be wandering around aimlessly in an unfamiliar house.

She had just reached Mokuba's door. She sighed, relieved. She hoped he wouldn't be too mad at her and would show her the way out. Serenity turned the handle to the door and –

(hee hee cliffhanger!!!)

(Just kidding!)

(Aren't I evil?)

(Okay back to the story where were we -)

(Oh yeah)

Serenity turned the handle and saw…. something that was definitely not Mokuba's room of video game madness. It was about the size of Mokuba's room, but that was where the similarities ended. The tall windows were covered in dark curtains, and the entire room was dark, with shadows forming from her body in the doorway. There were tall ceilings and it had a very dark feel to it. Lined up against the wall were boxes, a lot of boxes. Some were big, like trunks and some were very small, like hatboxes. It looked like a very private room, and she was just about to leave, when she saw a maid walking down the hall towards her.

She didn't know why, but she jumped inside the room and closed the door. It wasn't as if she was doing anything bad, but it seemed like instinct to her. She decided she might as well check out the room as long as she was in here. She flipped on a light switch so conveniently located next to the door and the room became illuminated. But the lights were dim, and it was almost as if she had not done any thing at all. She saw some candles by the fireplace, but didn't light them, as she didn't want to start a fire.

She walked over to the biggest box. It looked like an old trunk. It was brown with a treasure chest like feel to it. She opened it, not knowing what to find, but was surprised at its contents.

The chest was filled with pictures, letters, and random objects. Serenity wondered what the heck stuff like this would be doing in the Kaiba house. They didn't seem to be the sentimental type, to keep stuff. She sat down on the floor and pulled out a photo album. The cover was red and had a heart with a name in it. The name was Aiko. She opened the cover, and was surprised. There was a picture of Seto hugging a woman.

'Probably Aiko…whoever she is.' Serenity thought.

Aiko had short blonde hair with ribbons in it, and a perky smile. Seto was grinning, but something about his grin made Serenity uneasy. She turned the page, and found more pictures. Some were of just Aiko, her blonde hair blowing about her like a cloud, while others were of both Aiko and Seto. But every picture of Seto had that same weird smile. Serenity didn't know what to place it as. Was it happiness? She didn't know, because the Seto Kaiba that Serenity knew was cold and probably didn't even know the meaning of happiness, much less love. She shrugged and flipped thru the rest of the pictures. When she was done with that book, she put it beside her and looked at the rest of the stuff in the box. There were some red ribbons, probably from Aiko's hair, and letters. The letters were from Aiko to Seto, naturally she had kept his.

"Where had she gone?" Serenity wondered. She didn't really care. She felt like an intruder so she put the stuff back in the box and shut it with a bang. She pondered whether she should investigate the rest of the boxes. Would they hold more treasures from Aiko and Seto, or…? She tucked her hair behind her ears and opened the next box.
