Chapter 4: Error

Kagami was sitting with her other friends, Misao Kusakabe and Ayano Minegishi at lunch time.

"So Hiiragi, I notice that you've been sitting with us more often." Misao pointed out.

"Don't take it the wrong way." Kagami replied coldly.

"Did something happen between you and Chibikko?" Misao asked.

"As a matter of fact, Konata made a new friend. You know the one that's been popping in to see me about homework nearly every day?"

"No wonder. You're so dedicated to your studies that everybody wants to see you for help!" Misao implied in her usual teasing manner, which visibly annoyed Kagami.

"The point is that Konata doesn't seem to talk to me as much now because her new friend Samiko keeps studying with me, and gives Konata the answers to copy down."

"But of course. Now that Chibikko has a new friend to leech off she doesn't need you anymore." Misao stated. Perhaps she wasn't being serious when she said that, but for some reason, it really got to Kagami.

"Is that all my friendship meant to Konata? Was she only hanging around me to breeze through school because she was too into her hobbies?" Kagami was deep in thought.

"Regardless, Im really glad you can spend your time with us, Hiiragi."

While Kagami was spending her time with Misao and Ayano, Konata, Samiko and Tsukasa were sitting at their usual place.

"Sis hasn't been spending any time with us this week." Tsukasa said with concern.

"Yeah I know. It's just not like to her spend this much time away from us." Konata replied with the same worry.

"At least she still lets me see her if I have any problems. We seem to get along well." Samiko added.

"Samiko, if you're heading over to Kagami's this afternoon I'll come along." Konata requested.

Konata and Samiko arrived at the Hiiragi residence. It had been exactly a week since the two had arrived to study. The two otaku were greeted by Kagami once again.

"Hey. Come on in." Kagami offered, though her voice sounded rather dry. The three girls advanced through the Hiiragi residence, which Samiko was well acquainted to after coming nearly every day for exactly a week. She knew the Hiiragi parents quite well, though Inori and Matsuri weren't around often but knew her none the less. And of course she was all the familiar with Kagami's airhead sister, Tsukasa. The three girls entered the Hiiragi living room and immediately set-up for studying. Except for Konata of course.

"If you're not going to study with us, what was point of even coming here?" Kagami asked. Konata knew all too well that Kagami was a realist, but for some reason her voice seemed antagonistically aimed towards Konata. This didn't worry the blue-haired otaku though.

"Don't worry, I can just get some gaming in on your PS2!" Konata casually responded as she proceeded to switch on the Hiiragi's resident PS2 console.

"DON'T TOUCH IT!" Kagami suddenly roared. This unusual behavior attracted the attention of both Samiko and Konata, shocking the former. The latter had known Kagami for quite a while and usually knew what to expect, but not this. Something was wrong.

"What's wrong Kagami? You're not usually like this." Konata pointed out.

"FOR YOUR INFORMATION, I JUST REALIZED THAT THE ONLY REASON I WAS YOUR FRIEND WAS BECAUSE YOU COULD USE ME TO COPY HOMEWORK! BUT NOW THAT YOU HAVE SAMIKO TO LEECH FROM, YOU DON'T NEED ME ANYMORE, DO YOU! YOU'RE TOO INTO YOUR RIDICULOUS HOBBIES TO GIVE A DAMN ABOUT ANYTHING ELSE, SO YOU HAVE TO USE OTHERS TO GET THROUGH 'TRIVIAL' MATTERS SUCH AS HOMEWORK! DID I MEAN ANYTHING TO YOU BACK THEN, OR EVER!" After her outrage, Kagami took some time to catch her breath. Perhaps she could have continued her angry rant, but she didn't once she saw the state she had put her friends were in. Konata wasn't affected much, but was still shocked. Samiko and a rudely awoken Tsukasa had taken the brunt of Kagami's rant. Both of them were crying for their own reasons. Samiko was highly sensitive to sound, while Tsukasa on the other hand was scared that Kagami was acting this way.

"What have I done!" Kagami thought in guilt as she looked at Samiko and Tsukasa. Her yelling had indefinitely attracted the attention of her parents, Miki and Tadao Hiiragi.

"Is something wrong Kagami?" Kagami's dad had always had a calm feel about him but he never lost any firmness about him. Having attracted the attention of her parents made Kagami panic on the inside. She just knew she was going to get it. Surprisingly enough, she began to break down in the same way as Tsukasa and Samiko. Kagami's parents then turned to Konata, who was the least affected by everything that had happened.

"By the looks of it, these girls must be going through something. If you don't mind, could you leave us to discuss the problem with them?" Tadao requested to Konata. He tried to say it in a way that didn't sound rude. Konata did what she was told without any ill will and moved to another room of the house.

"Perhaps Kagami's right. Relying on her for getting any homework done. I always thought she was the kind of person that could put up with a lot. But it's not like what she thinks it is. My friendship with Samiko. If only I could make her understand." Konata thought to herself doubtingly.
