Author's Note: Actually it's my first story in English. I've always written essays for English classes so it's my first trial. I've tried to make it as correct as possible by myself, but I'm not sure if I did it well, so feel free to correct me :)

Prolog

"Oh," sighed Iruka when he came back home to see his lover sitting on the floor with a teapot filled with hot, aromatic tea.

One may say there's nothing strange in the picture Iruka had seen, but… If someone have known Kakashi better, he would realize it's uncommon to see him calmly sitting in the living room and drinking green tea.

Kakashi didn't even like green tea!

The jounin was dressed in the pale-blue yukata made of soft, expensive cloth. Iruka had never seen him dressed like that and beside that, he didn't even know Kakashi had something elegant to wear. The only clothes Iruka had seen in a wardrobe were his jounin uniforms, he didn't even have any casual clothes. Silver-haired was holding a little tea cup. The cup looked almost like a toy in his big, masculine hand.

And if that wasn't too much for poor chuunin, he wasn't even drinking the tea. He was sipping it carefully and his uncovered face expressed something Iruka would call pure ecstasy.

Iruka pretended not to notice.

After all, Kakashi was a jounin. Every jounin had something wrong with their minds. Every single one of them was strange. For example – Genma have never stopped sucking his senbon. Even unconscious. One nurse didn't want him to get hurt, so she tried to pull the senbon away from his mouth. He was still unconscious while he twisted her wrist. Anko was hyperactive, addicted to sex and loved to gossip. She knew everything about an intimate life of all Konoha shinobi. And Gai… Well. Gai was just being himself.

And Kakashi was no different.

Firstly, he wore a mask and had only one eye visible for the world. Iruka was probably the only person who was able to read jounin's emotions so perfectly. He could tell what kind of emotions Kakashi's face showed. The Copy Nin didn't like sweets. They made him fell stomachache. He had a strange habit to leave a jar of coffee in the fridge or soak his toothbrush in the lemon juice because he heard it kills bacteria. He also didn't see anything wrong in reading porn right before children eyes.

"Would you like some tea, Iruka-sensei?" Kakashi asked quietly while Iruka had been trying to slip into the kitchen unnoticed. Iruka bite his lips feeling jounin's gaze on his back. Not good. Not good at all. Whatever freaking thing Kakashi had in his mind, Iruka didn't want to have anything to do with it.

"Tea. Would you like some?" Kakashi repeated, glancing at Iruka who slowly turned around to meet his lover's eyes. Hatake had pulled up his mask just in case someone might make an unexpected visit.

"Yeah. I mean… If it's not a problem."

"It's my pleasure, sensei."

Iruka blinked, following every move of Kakashi, watching as he gently takes the kettle and slowly fills the cup with a tea.

Chuunin scratched the scar on his nose, staring at the jounin who finally put the tea cup on the table between them. Once again the thought of how big his hand was comparing to the little cup hit Iruka.

"May I ask you what's that show for?" chuunin asked hesitantly. With a questioning look he was moving the tips of his fingers over the edge of the porcelain cup.

"Show? Maa, Iruka-sensei… This is what well-mannered people do in the evening," Kakashi slowly pulled his mask down to take a little sip of tea. He did it so slowly, that the gesture seemed unbelievable dignified. "Don't you think?"

"Stop calling me 'sensei', Hatake. Everyone knows you're far from being well-mannered."

"From today I am…"

"You're nothing but ridiculous today, Kakashi," Iruka interrupted him, making irritated face. "Where's that stubborn, rude jounin I left here this morning?"

"Don't you dare saying I can't be well-mannered…!" he raised his voice, frowning a little.

"Raising you're voice isn't polite, Kashi," Iruka reproved him quietly.

"Oh, I can be polite if I want to," with one look in Kakashi's eye, chuunin could say that he was pouting. "I'm just… I just have to divide myself in two. I mean… The real, polite me and shinobi me."

Kakashi muttered something to himself and picked up the tea cup. If he wanted to look elegantly in the evening, he had definitely done it wrong. His hair was spiky as always. He seemed as if he had no clue what an obi is, because he didn't tie one on his yukata. He just had worn it as if it was a some kind of robe. And the sleeves. The dark cloth was sticking out of the sleeves rolled up above his elbows.

Maybe mission Kakashi has came back lately went terribly and now he's acting strange cause he can't get over terrifying him memories – Iruka shook his head. That wasn't the point.

Carefully, Iruka lifted the cup, taking a little sip. His eyes went wide and he almost spat it out on the fluffy white carpet. The tea tasted disgusting. Anyone in their right minds wouldn't put sugar into green tea. There was no need to add it - even if green tea is bitter sometimes, sugar makes it taste awfully. Iruka swallowed it down but didn't say anything. Offended Kakashi was the last thing he needed now.

"Listen, Kashi. You can't be well-mannered with your yukata dressed like that," he stated shyly, watching as Kakashi face flush gently. "And… you have to learn, that…" Iruka silenced, looking for the right words. "Sugar makes us unable to feel the unique taste of green tea."

"You still think I can't be well-mannered," Kakashi snorted and took off the yukata. He was even wearing a sweatshirt with Konoha sign. "But, believe me, I can be well-mannered. Wanna bet? Just give me a month and I'll have better manners than those Hyuuga brats!"

And with those words Kakashi left the apartment. Iruka was sitting motionless on the floor in the living room, staring with disbelief at the place where jounin was sitting just a moment ago. He didn't even expect that Hatake was doing his research in a library, looking for a good books about savoir-vivre.
