Mugen lay awake, sleep seeming so insignificant at the moment. It had been a rough day. Even Jin had been affected by it, and he had gone off to "meditate." Mugen sighed.

They had almost lost Fuu.

Some son of a bitch had nearly speared Fuu through just to get back at Mugen. Who he was, Mugen still didn't remember. He did remember, however, hacking that man to pieces.

He looked over at Fuu's curled form. She was so small, so fragile. Mugen clicked his tongue in annoyance. Stupid bitch. He didn't know why he was so affected by her, why he let himself sink this low – to be so concerned with some dumb girl's well being.

It didn't help knowing four-eyes felt the same way. Instead, it filled him with a jealousy he could not comprehend. It seized at his chest and made his stomach churn and lurch violently. It made his life with the other two even more unbearable than it already was.

Mugen felt something curl up against him, and he nearly lashed out.

"Mugen…"

He froze in place as he realized what had just happened. Fuu had cuddled up to him in her sleep and muttered his name. Mugen had no idea what to do.

It did get cold at night, and Fuu was weak to the cold – this was not news to him. Still, did she have to press her slender body against his? Mugen cursed under his breath, careful not to wake her and turned to face her.

Unfortunately, Fuu had chosen today to be a light sleeper (which she was completely not!). She stirred and whined sleepily, nuzzling her face into his chest. It was such an affectionate gesture, and Mugen felt his stomach clench. Unfortunately, Fuu was finally fully awake.

Fuu gasped and pounded her fists against his chest. "Mugen, you pervert! You just let me cuddle up to you! Why didn't you wake me-"

"Shut up," he growled, and he crushed his lips to hers. Fuu inhaled sharply, but she melted against him instantly, her fists relaxing. He kissed her insistently, and she moaned in response. Her cool breath was fanning his cheek, and he pulled her closer, hands encircling her waist. Her hands reached up to thread themselves in his hair, and he groaned at her touch.

The door slammed open, and the two immediately parted, turning their backs to each other. "I'm back," Jin said flatly. "Move over," he demanded, pushing Mugen away with his foot and placing himself as a barrier between Mugen and Fuu. "Good night."

"Feh!" Mugen exclaimed, but his face betrayed his displeasure and embarrassment. "Whatever!"

"Sweet dreams…" Fuu said quietly, and Mugen let out a deep breath.

Yeah, he'd definitely be having some sweet dreams tonight…

fin.

Fuu and Mugen are still my ultimate OTP. So here's another oneshot after like...2 years. Reviews and favorites are always appreciated!
