In the Dya manga, Yuuko lounges around in her underwear at home.

Feeling sick, writing anyway. This does not bode well.

'Bed smells so nice', Hideyoshi thought to himself as the sleepy haze in his mind began to diminish. Today is a perfect lazy morning – no school, no chores, nothing to worry about. Even if Hideyoshi was starting to wake up now, he'd just find a new comfortable position and drift back to sleep.

Until he rolled over and hit something that wasn't supposed to be there, that is.

Startled, he flew backwards, jerking the covers away from himself and the foreign object in the process. Reluctantly, Yuuko sat up to glare at him. Hideyoshi blinked a few times in astonishment, then quickly looked away as he recovered his senses. He was blushing when he spoke. "S-sis?"

It was apparent even to him that his voice wavered, and he sounded as if he were in suffering from some strange mix of fright and surprise and anxiety. There were many responses to this that he expected to hear from his twin. It would have been perfectly normal for her to snap at him, something along the lines of, "What do you want!" or "Don't look at me like that!" or some other equally abusive remark. What he didn't expect was silence, and it unnerved him.

Cautiously, he chanced a glance back at Yuuko. Her gaze was averted from him and her arms wrapped around her body, as if for comfort. She looked strangely vulnerable, and Hideyoshi had to pinch himself to make sure it wasn't a dream.

A sharp pain developed in his arm, and the skin was probably going to bruise later, but Yuuko was still sitting in front of him the next time he opened his eyes. For a brief moment after that, he wondered if he had accidentally stumbled into Yuuko's bedroom sometime last night. It seemed unlikely, and a brief glance at the walls confirmed the impossibility; those were his posters on the walls, his magazines stacked in the corner, and a completely clean desk, compared to Yuuko's, whose was usually piled with clutter. Aside from his sister, everything seemed in place …

"Sis, is something wrong?" he tried.

He didn't receive an immediate answer, and he wasn't sure if he should have expected one. Even after waiting, the silence remained like a heavy smog clogging the air. From the quick glances he was able to cast at her every few seconds, Hideyoshi could tell that she wasn't moving. He sighed grimly, unsure of what to do or what was causing this unorthodox behavior in his sister.

"You should really put something else on," he mumbled idly, without really thinking. "Even if it is our house, it's not okay to run around in your underwear …"

"That is definitely something you would say," Yuuko scoffed, though so quietly he almost didn't hear it.

" …Sis?"

Every time Hideyoshi begins to think the situation can't become anymore shocking, Yuuko does something to prove him wrong. When Yuuko finally turned to look at him, Hideyoshi thought he saw water in her eyes. Looking twice confirmed to him that he was not hallucinating, and since he was obviously not dreaming anymore, he has to force himself to accept something he thought nearly impossible – his sister was on the verge of crying. Regardless of how she's dressed, he finds himself wanting to hug her – if only his sister were as easily comforted as that.

"S-sis? What's wrong?" he questions again.

Hideyoshi is mentally running through a list of possible reasons when he hears Yuuko say something, but it comes out as barely even a squeak. He has to ask her to repeat it, even though it makes him feel guilty doing so. But he doesn't hear it the second time either, and he's afraid to ask for a third time.

"I-I'm sorry," he mumbles uncertainly, as if Yuuko might understand that he just couldn't get it.

Without warning, Yuuko suddenly lurches forward and clings to him with a stiff embrace. Hideyoshi responds instinctively, hugging her back and fretting over how tense she feels. Whatever has Yuuko worried must be fairly big, since she's never as tense as this. Just like his actions, his words come instinctively now; "Sis, I'm right here for you . . ."

Yuuko shuffles against him, and wipes her eyes with her forearm. "And will you stay there?" she mumbles shyly.

"Of course," he replies; it is an answer that requires no thought. "Sis, why don't we just … go back to bed?"

He's still confused as to what's going on, but he somehow senses that it's better not to ask. But despite what his instinct says, Yuuko tells him anyway once they've both lied down again.

"I've missed you," she says as Hideyoshi pulls the blankets back up.

"Hm? I don't understand . . ."

For a moment, Yuuko is tempted to tell him everything, and Hideyoshi vaguely thinks back to the all the time they used to spend together. But the idea is dismissed, and instead she says, "It doesn't matter. I have you back now, and that's all that counts. And I'm never letting go again."

. . . This story was a bit rough, but not too bad. Not sure how I feel about the ending though. Opinions?

Writing a defenseless Yuuko is a bit weird.
