Hello everyone! I'm so sorry that I haven't posted anything in a while! I just had a MASSIVE writer's block and a lack of motivation. However, I'm slowly getting back into the fandom, so I'll try to write more from here on out!

Anyhoo, this is once again, 2p!China/2p!Japan, so they won't be exactly like their 1p! counterparts. And...I decided to attempt fluff with these two, so here you go!

DISCLAIMER: I own no part of Hetalia whatsoever.

Chemical Reaction

'Almost done...' Yao thought as he poured the contents of a vial into a nearby beaker. It was about four in the morning as he continued making yet another lethal poison. He had now been working on the concoction for about three hours now, and he wanted to see the fruits of his labor.

Lost in his work, the brunette didn't notice his lover standing by the doorway.

"Shouldn't you be asleep by now?" a man by the door spoke, almost making Yao drop the vial he was holding.

"What are you doing here, Japan?" Yao asked, placing the now empty vial in a rack. He turned around to face the younger man, quirking an eyebrow at the sight of the other man wearing one of his shirts.

"Oh come on, you don't have to call me that here, right? The others aren't around." Kiku said, leaning against the door frame.

"Yes, I know that. However, I don't want to slip up in a meeting. Do you know what would happen if the others found out about us?"

"Of course I know. You won't let me forget it, after all." Kiku replied, frowning slightly. "Why do you care about what they think anyway? I thought you considered yourself above them. What happened to the mighty Middle Kingdom?" he added.

"Nothing. The Middle Kingdom is still here, he's just mellowed out a little."

"Heh, if you've truly 'mellowed out', then you wouldn't be making poisons to harm the other nations." Kiku teased, walking toward the other man to peer over his shoulder.

"I'm not making these to kill them. It's my hobby." Yao defended.

"Your hobby to assure you have an advantage over the others."

"No, not a way to assure I have an advantage. It's just something to...relax me."

"Relax you by killing the other nations, you mean."

"Of course not. The only reason I would use these to harm the others is if they tried to hurt you."

"Aw...you do care about me!" Kiku smirked, throwing his arms around the other male.

"Yeah...I guess I do. Now let go of me so I can finish this poison. I can't focus on anything with you around." Yao said, unfazed. He shrugged the other male off of him, picking up another vial to continue his work.

"Oh, so do I distract you?" Kiku continued to tease.

"If by distract you mean perpetually annoy, then yes, you do."

"That's mean, Yao."

"Would you expect me to be any other way?"

"Haha, of course not." Kiku chuckled. "I guess I'll leave you to your work, just don't stay up all night. Remember, we have a world meeting tomorrow."

"Yeah, maybe there I can test some of these." Yao replied, glancing toward the various poisons lining the table.

"Yao..."

"Oh calm down, I was only joking. I'm sure poisons wouldn't effect them anyway."

"Hm...alright, but finish up soon. I would love to have your company in our room."

"Alrigh- wait. What?" Yao swung around again, only to see Kiku leaving. The Chinese man sighed, shaking his head.

"I'll never understand you." he mumbled, once again turning back to his work.

...Writing fluff with these two is weird. Meh.

Anyway, thank you for reading, and any feedback is greatly appreciated! Have a great day, everyone!
