To start it off, I just want to clear any misunderstandings about the last chapter :
Apparently, not surprisingly, there was some confusion around the whole Ryuuji's father thing.
The letter was really just for comic relief, to kind of show that his father was in reality, a slightly weird, childish guy. Somewhat like Gai in Naruto. Another question was, why Ryuuji answered Taiga with an "I think so" to her question about them being a couple, instead of "of course." Basically, I feel that Ryuuji is afraid to make pre-assumptions on Taiga's feelings, and therefore tries to stay a little back to make sure he doesn't go to fast, or hurt her.
Anyways, I'm done with both exams and oral exams now, so I think I'll be able to write a lot more now.
Also, I want to try and lengthen my chapters a little, more like the one I posted the last time.
Anyways, on with the story ~

Ryuuji awoke from his former peaceful sleep by a loud noise from the living room.
"What the hell is it now?" Ryuuji asked himself with a grumpy voice, too tired to really make any sense of anything. He walked into the living room, his entire body swaying back and forth, and he sighed as he saw Yasuko lying flat out on the tatami mats.

He rubbed his eyes and walked over to her, crouching down next to her.
"It's 4 am, and you decide to pass out before reaching your room. That's just great," Ryuuji said with a sigh, putting Yasuko's over his shoulder, supporting her as he lead her into her bedroom. He lay her down on the futon, turning around to leave.

"Such a nice son," Yasuko mumbled with a happy, drunken voice. Ryuuji sighed again as he left the room, heading back to sleep.

'I'm going to be absolutely exhausted,' he thought to himself as he lay down on his futon again, trying to fall back to sleep. At the same time, Taiga slept peacefully, curled up like a ball in her big bed. Yet again, she had a dream having to do something with Ryuuji and food.

"Pork cutlet.." she mumbled, moving slightly around in her bed.
"Give me pork cutlet."

…

3 hours later, Ryuuji was awoken by his alarm clock. He stretched his arms and yawned loudly, standing up from his futon. As he would always do, he tiredly shuffled his feet over the floor, wearing only a t-shirt and boxers. He rubbed his eyes as he entered the kitchen.

He tiredly hummed away to a tune as he started preparing breakfast as if he was programmed to do so. He practically didn't realize that he was even making breakfast before 10 minutes into it. After putting down the heat on the stove, he left the vegetables to fry for a moment as he headed into the bathroom for a quick shower. After he was finished, he quickly finished breakfast and lunch, packing the lunch into tiny bento boxes.

'She's late', he thought as he looked at his watch. He hurriedly pulled on some pants and a shirt before walking over to Taiga's apartment, finding her door slightly open as always. He sighed as he walked into her bedroom, finding her fast asleep. He crouched down beside her bed and leaned his chin on the mattress, just looking at her for a while.
'She looks like a doll,' he thought to himself upon seeing her sleeping figure.

He heard a faint voice somewhere, but he didn't know what it was. He could hear it get clearer and clearer, someone calling out his name.
"-uuji," the voice sounded, "Ryuuji! Are you listening, you perverted dog!" Taiga shouted as she slapped him across the face with a pillow.

"Ah.." he said as he finally came to. He had somehow dozed off, only for a minute or so.
"I was going to wake you up, but then.. Anyways, breakfast is ready, and we're already close to running late," he said, poking Taiga's nose. She flinched a little.

"Okay, then," Taiga said with a reluctant voice, still sounding slightly tired.
Ryuuji stood up and turned around, ready to leave the room, as someone grabbed the edge of his shirt. He came crashing towards the floor, face first, as Taiga fell over him. She crawled over his back, making him grunt in pain several times, before standing up and walking towards the door.

"Eh," she uttered, turning around with an incredulous look on her face.
"How did you end up on the floor, Ryuuji?" She asked with a confused, high pitched voice. Ryuuji grunted again as he stood up.

"You.." He growled, but stopped himself.
"Good morning." He said with an annoyed voice, and Taiga came towards him, shuffling her feet.

"Thanks for waking me," she said with a gentle voice as she left a kiss on his cheek and left the room.

'How can she change so fast just because she's tired?' Ryuuji thought as he shrugged his shoulder.
'Beats me.'

Taiga suddenly returned to the room, holding a hand on her stomach.
"Ryuuji," she said with a groan, "I don't feel too good."

…

Lunch break had arrived, and Taiga sat in her chair with a tired look. Ryuuji came walking to her desk, sitting down with her, and so did their other friends.
"Really, you didn't have to push yourself," Ryuuji said as he sat down next to her. Kushieda jumped on her and hugged her tightly, faking a cry.

"Poor Taiga ~" she howled, making Taiga blush a little.

"M-Minorin, it's okay!" she said, pushing her back a little. As they fumbled around, Kitamura turned to Ryuuji.

"Hey, Ryuuji, I have something to ask you," he started, looking almost a little nervous, "so maybe we could meet up later?"
Ryuuji looked a little surprised, as it wasn't really like Kitamura to ask him for help with anything.

"S-sure, just call me whenever," Ryuuji said, lifting an eyebrow. Kitamura smiled at him and turned to his lunch.
'Anyways, isn't it unusual for him to call me by my first name, even though we're friends?' Ryuuji thought to himself, but brushed the thought off.
Ryuuji looked up as he heard Ami speak with a slightly concerned voice.

"I'm sorry, but I'll have to take this one out in the hallway and ask her something," she said with a silly smile as she pulled Taiga's arm. She didn't even have time to resist before she was pulled into the hallway by Ami.
Ryuuji frowned and looked towards the door.

"What could it be she wanted to talk about?" Ryuuji asked, but it didn't take long before he heard a loud voice coming from the hallway.

"W-w-why would you ask such a stupid question, you stupid Chihuahua!" Taiga shouted. Not long after, she came tramping into the classroom. Just as Ryuuji tried to speak up, she walked straight past him and grabbed her bag, rushing out of the classroom. It looked as if there was fire on the way out of her ears. Ami came over with a sigh and slumped down on her seat, sighing deeply.

"W-what did you say to her?" Ryuuji asked with a bitter smile. Ami shrugged.

"I won't say it out loud to a boy, you know," she sighed. Ryuuji frowned and stood up.

"Hey! I feel like I have a right to know what's going on," he said with a grumpy voice. Ami sighed again and stood up, grabbing Ryuuji's arm.

"I'll only tell it to you, then," she said, pulling him back out of the room. As they came into the hallway, she let go of him and turned to him with a serious look on her face.
"I asked Taiga whether or not she had her period yet," Ami said, "seeing as she wasn't feeling too good."

Ryuuji furrowed his brows before realizing what Ami was talking about, which made his eyes practically pop out of his skull.
"Y-you asked her what?" he almost shouted at her face, his cheeks turning red, "Why would you ask such a thing just because she was feeling sick?"

Ami shook her head and sighed yet again, putting a finger to her lips.
"Something tells me the two of you spent Valentines day together," Ami said with an innocent, teasing voice, and she puckered her lips. Ryuuji frowned and waved his hand slightly back and forth.

"We didn't do anything like that, you know," he said, sounding calmer.
Ami shrugged and looked to the side.

"Well, I would go as far as to say this is my business, so I guess I should tell you," she started, making Ryuuji look a little bewildered, "before she started shouting, she said she did in fact not have her period yet, so lying to me won't help anyone."

Ryuuji widened his eyes and took a step back, his eyebrow twitching.
"B-but," he stuttered, "we didn't do anything."
Ryuuji was almost certain that it was just a coincidence, but there were some unpleasant thoughts invading his head, but he would never go as far as to assume that Taiga would cheat on him.
'That wouldn't be like her in the slightest!'

Ami shrugged and looked to her right side, seeming careless.
"Oh well, she doesn't seem the type to cheat on her boyfriend or anything, so you don't need to worry about anything like that," she started, "but of course, I'm not sure if you're telling the truth."
She smirked at him, making him blush a little.

"I'm telling the truth," Ryuuji mumbled, scratching his hair.
"Maybe I should find her." He said.

"I'll come with you," Ami nodded. Ryuuji was about to protest, but Ami put a finger up, signing for him to stay silent.
"You might need a girl in this situation, Takasu-kun ~" she said with a deceiving voice, making Ryuuji sigh before shrugging his shoulders.

"Very well, then, but don't blame me when the teachers scold you for skipping classes." Ami chuckled a little from Ryuuji's remark, but didn't seem to care.
They returned to the classroom and picked up their bags, before walking over to Kitamura and Kushieda.
"We're going to go look for Taiga," Ryuuji said with a calm voice. In a matter of seconds, Kitamura and Kushieda were on their feet, bags in hand.

"We shall join you!" They both exclaimed in unison, making Ryuuji take a step back in surprise.

"A-are you sure?" Ryuuji asked, making the two take position as if they were in the army.

"Yes, sir!" They almost shouted, making both Ryuuji and Ami sigh as the entire class stared at them.

"Just calm down, and we'll go," Ami said with a reluctant voice. Kitamura and Kushieda nodded vigorously as Ami turned to leave. Kitamura, Ryuuji and Kushieda followed close after, Kushieda and Kitamura still seeming very energetic. As they had left school, they tried to find out where to go.

"I say we check her apartment first, that's the most likely place she'd go to," Ryuuji said, and the others agreed. They started walking, and it took a while before anyone spoke up at all.

"What did you even tell her to make her react like that?" Kushieda suddenly asked with an almost scary voice, the undertone saying 'What did you do to poor little Taiga?'

Ami shrugged and looked to her left, turning her face away from the others.
"I only asked her a simple question, and she seemed to get very embarrassed about it." She said, sounding like she didn't really care at all. Kushieda muttered something under her breath, and turned her face away from Ami. The rest of the walk was spent in silence.

They arrived at Taiga's apartment, and they walked towards her door. It was actually closed this time, and Ryuuji started knocking.
"Taiga?" He asked, "Taiga, it's me, Ryuuji." He knocked again, but there was no answer. He turned to the others, and they just shrugged their shoulders.
They left the apartment complex and stopped outside, looking around.
"Alright, before we look any more, I have to go inside and get something," Ryuuji said.

"Okay, we shall wait here, Takasu-kun!" Kushieda exclaimed. Ryuuji nodded and walked up the stairs to his house. He tried opening the door, but it was locked.
"Huh? That's weird," he muttered as he grabbed his keys out of his pockets. He opened the door and let himself in.
He walked around his house to see that Yasuko wasn't home. He found a note saying she had left early for job.
Ryuuji remembered that he had to get something from his room, so he went inside. He started looking through his desk, and suddenly heard a grumpy sound behind him.

"Eh?" He uttered has he turned around to see something moving under the blankets on his futon. He lifted an eyebrow as he walked towards the wriggling figure, and he lifted the blankets to peek underneath. He was met with a pouting face.

"What?" The little girl asked with a grumpy voice, looking at Ryuuji.
Ryuuji sighed and pulled the blankets all the way off. Taiga sat up and crossed her arms over her chest, looking at the wall to her right.

"What are you doing here?" Ryuuji asked, looking at her as he sat down on the floor in front of her.
"And how did you even get in?"
Taiga pointed towards the balcony, signaling that she climbed there from her own window. Ryuuji sighed.
"Did Ami's question make you that angry?"

"It was embarrassing," Taiga muttered, letting her arms dangle over her legs.
"I mean, why would she even ask such a question? Does she want to make fun of me?"

"It wasn't to make fun of you," Ryuuji said with a serious voice, "it would be pretty serious if she was right, you know." He sounded a little concerned.
Taiga looked at him with a confused expression.

"Why would it be serious?" She said, "And she was right, wasn't she?" She pouted and looked down. Ryuuji widened his eyes a little, having no idea what Taiga meant by this.

"You do know what it means when you don't have your-" Ryuuji hesitated before using the word, as it was a little embarrassing, "-period for a long time, right?"

Taiga looked up at Ryuuji with a bewildered expression, before widening her eyes.
"IDIOT!" She shouted, slamming her fist towards Ryuuji's chest. He fell backwards and landed with his back towards the wall.

"W-what are you doing?" He asked with gritted teeth, trying to shake off the pain. Taiga came walking towards him with a furious expression, making Ryuuji seem very scared. She stood over him, closing her eyes in embarrassment.

"W-when I said hadn't had my period," she said with a panicking voice, "I meant I never had it, never ever!" Her face turned red as a tomato, and Ryuuji looked confused for a moment, before realizing what she meant.

"O-oh." He uttered, looking surprised. Taiga gritted her teeth and look down at Ryuuji.

"So, are you going to make fun of me now?" She asked with a serious but shaky voice. Ryuuji smiled a little and grabbed her hand.

"I don't have any reason to make fun of you," Ryuuji said with a gentle voice, striking his thumb over her hand.

"B-but I'm so immature," Taiga said, pouting. Ryuuji sighed and pulled her down, making her sit down over his lap. He looked her in the eyes, and she still looked embarrassed.

"It's not your fault that you're late, Taiga." He said with a firm voice. Taiga sighed and let her head fall to his chest, her forehead leaning on it.

"But it's still embarrassing, you know." She mumbled, and Ryuuji smiled.

"Don't think too much about it," Ryuuji answered. He put a finger to her cheek and lifted her face so he could look her in the eyes.
"You know that I love you no matter what, right?"

Taiga nodded, embarrassed. Ryuuji smiled again and pulled her closer, their lips meeting. Taiga wrapped her arms around Ryuuji's neck, and he put his arms around her back. They stayed like that for a while, their lips still meeting in rising speed.

"Are you okay? We heard a loud noise, and-" Kushieda and Ami stood in the door, a blush creeping over their faces as they saw the couple close to the wall. Ami smirked at Ryuuji, and Kushieda stood there, frozen.
"You two are so vulgar," Ami said with a teasing voice.

"A-ah.." Taiga uttered with an embarrassed expression. A smile started creeping onto Kushieda's face, and a thin stream of blood found its way out of her nostril.
They looked at her in complete silence, as she lifted her arms to her chest and opened her mouth.

"KYAAA ~" She exclaimed, "My mind can't stand something so cute! ~"
Ami sighed, and Taiga's face turned even redder. Ryuuji sat there with a bewildered expression, not saying anything.

"S-stop it, Minorin!" Taiga uttered, "It's embarrassing!"

I am so sorry it, it took such a long time for me to finish this chapter!
Oh well, at least it's here now. Considering I want at least some character development, I started building up to a chapter involving more Kitamura, when he asked Ryuuji for help.
I'm not sure what to do about it yet, but at least it'll hopefully bring some development.
