My Best Friend's Girlfriend

Chapter 2: Cracks Beneath the Surface

Yolei Inoue

"Really, Yolei. I wish you wouldn't do that."

Yolei rolled her eyes and tried not to smile. Since when has Sora become such a stick in the mud?

The two of them were walking side by side, books in hand, heading for their lockers. Her first day of school had been pretty much the usual, unless you counted the fact that Matt had been suspiciously absent from the cafeteria the moment Jun had walked through the doors. He should learn not to be so obvious.

"Do what? I didn't do anything," she replied.

Sora sighed, her amber eyes filled with disapproval. "Flirting with Matt. You know I don't like it."

"Where did you come up with an idea like that?" Of all the nerve! Okay, so maybe I had been flirting with him, but it had been entirely for fun. He does look cute when he blushes, and there's no denying that he's handsome. What's wrong with pointing it out?

"Lighten up, Sora. I was just kidding around. If you want to yell at someone for flirting with Matt, yell at Jun, not me!"

Sora's face finally relaxed into a smile. "Sorry. Jun's got me a little paranoid, that's all, and I wasn't yelling," she scolded, playfully poking Yolei in the shoulder.

"I don't blame you. All the girls are after him. Speaking of Jun, did Matt ever tell you how that date went last school year? I've been trying to get it out of him for ages, but he refuses to tell anyone."

"Yeah, it really was a disaster. Jun kept embarrassing him the whole night. Matt doesn't like to talk about it."

Now this is juicy gossip! "Did she kiss him?"

"Attempted to," Sora sighed. "She never succeeded, though not for lack of trying."

Poor Jun. Score one for Sora. Yolei almost felt sorry for Davis's sister.

"Anyway, like I said, Matt doesn't like to talk about it. I think Tai was the only other person he told."

"Naturally, they're best friends," Yolei replied.

"Yeah," Sora said slowly, frowning.

Yolei stopped walking and turned to give her friend a curious look. "Sora? Is something wrong?"

Sora shook her head and managed a smile. "No, not really. Maybe I'm just imagining things."

"What do you mean?" Yolei asked, feeling confused.

Sora glanced around, as if concerned that someone would overhear them, and pulled Yolei out of the crowd against a water fountain where there was less noise.

"I don't know if you've noticed, but don't you think that Tai has been acting a little strange lately?"

Yolei wrinkled her nose and frowned. Now that she thought about it, Tai had been acting a little more edgy than usual. Normally Tai was very laid back. He was usually very happy and energetic, so why had he become quite snappish all of a sudden? "Er...now that you mention it, Tai has been a little more moody than usual. I thought that was more Matt's style. What do you think is up with him?"

"I have no idea," Sora said softly. "All I know is that something doesn't feel right."

Yolei was about to reply when she heard someone calling out their names.

"Yolei! Sora!"

She turned and spotted a head of bright pink hair weaving towards them through the crowd. It was strikingly visible against the sea of brown, raven, auburn, and gold tresses.

"Hey, Mimi! How's it going?" Yolei had to smile at her friend's obvious enthusiasm. She was glad that Mimi had moved back to Odaiba. It was so much easier to hang out and talk about boys. It was nothing against Sora. Yolei loved the other girl. It was just that sometimes Sora acted a little too serious for her taste. Maybe Matt's rubbing off on her or something.

Mimi, on the other hand, knew how to have a good time. Currently the rosy haired Digidestined was dressed in a pink top, black knee-length boots, and a black and pink Scottish style skirt.

"Hey, Yolei. So, how did the first day go?" Mimi asked. She sounded slightly out of breath and had to take a moment to compose herself.

"It was okay. The best part is that there are a lot of cute boys here!"

"Aren't there? Just as many as back in New York!" Mimi laughed and then let out a soft sigh, a smile forming on her pretty face. "I still miss Michael and the rest of my friends, but the truth is, I missed you guys even more. New York was great, but Odaiba will always be my home. It's awesome to be back here with you guys. I really did miss you all."

Sora gave her best friend a warm hug. "We missed you, too, Mimi. It's good to have you back."

"No kidding! This is perfecto! Finally I have someone to go boy watching with me!" Yolei grinned. "Sora can't, she's taken,and Kari's in la-la land over T.K. even if she won't admit it!"

All three girls laughed.

"So what are you guys up to?" Mimi asked.

"I'm heading over to meet Kari and the others at the elementary school," Yolei announced.

"Okay," Mimi replied. "I have to go find Izzy. We promised Tai that we'd go to his soccer practice, that is, if I can actually get Izzy to stay off his laptop long enough to pay attention! Maybe I should 'accidentally' spill something on it. It might get him out of his own little techno world for a while at least!"

"That would certainly get his attention!" Yolei laughed.

"What about you, Sora?" Mimi asked.

"I better go find Matt," she said quietly.

Yolei shrugged as Mimi glanced in her direction.

"Um...Sora? Are you okay?" Mimi asked hesitantly.

Sora managed a rather weak smile. "Yeah, it's not me you should be worried about. I'll see you guys later."

Sora quickly left leaving Yolei and Mimi to stare at each other in surprise.

"What's going on?" Mimi asked, looking concerned.

Yolei just shook her head. "I have no idea. Everything was fine until I mentioned Matt and Tai. Then she started acting really weird."

"Oh," Mimi said softly. "So that's it."

"Huh?" Yolei gave her a look of confusion. "What do you mean?"

"Nothing," Mimi replied with a wave of her hand. "It's just, I guess Sora must have noticed, too."

Yolei frowned. "Noticed what?"

"Tai," said Mimi with a deep sigh. "Haven't you noticed? He's been acting like a total nutcase. I'm worried about him."

"Sora did mention something about that. What do you think's going on with him? Sora doesn't have a clue."

Mimi made a face. "I don't either."

"Why don't you ask Matt? He might know." Yolei suggested.

"Actually, I don't think that Matt does know," Mimi said slowly.

Yolei gaped at her in surprise. "You're kidding, right? They're best friends! They tell each other everything! Seriously, Mimi, I swear sometimes they can communicate without even saying a word. If anyone would know, it would be Matt."

"Exactly," Mimi replied. "That's what makes everything worse. I'm pretty sure Matt doesn't have a clue about what's going on, and that scares me most of all. You've seen Matt. He hasn't been acting any different towards Tai than he usually does. If he knew about something that was making Tai act so crazy, I'm pretty sure it would be a different story."

"Matt did ask Tai if he was okay today," Yolei countered. "He must suspect something."

"Maybe, but if Matt did know what was going on, then why would he be asking Tai if he's okay?"

"You're right. Well, what are we going to do about it?" Yolei asked, feeling a sudden rush of concern.

"There's nothing we can do, not until Tai wants to clue us in," Mimi replied. "Speaking of Tai, I better go before he throws a fit about me being late. I'll see you later."

"Okay. Bye, Mimi," she called out, watching her friend disappear through the crowd.

Weird. Why would Tai not confide in Matt? She shrugged. And I thought guys were suppose to be less complex. So much for that theory. I guess I'd better go catch up with Kari and the others.

She turned and headed off down the hallway, her lavender hair bouncing as she walked.
