You might be wondering who the human was, a killer a mercenary or a simple human?
Well, he was the simplest human you can think of, a 23 years old Japanese kid who had transferred in New York a week prior and got lost in the city.

Our beloved angel was walking around his massive apartment on 5 floors when he saw the human wandering in the lower. He smirked, until he saw the little human's face, two deep black eyes, soft features and a pair of plumpy pouty lips. Immediately his eyes widened and he ran to the entrance of his apartment, the young boy was only one floor under.

As the boy was in front of the doors he opened them with a snap of fingers. "Sorry sir, I-I got lost a-and " the younger started but he interrupted him. "Beautiful, don't worry, come here, are you alone?" He asked with a soft voice holding his hand out for the boy to grab. The younger blushed but nodded grabbing the hand.
"I'-I'm Yuki" He said as soon as he was inside before the other snapped his fingers again closing the doors and scaring the boy a bit

"The name is Yasha, my beautiful snowflake, come" The angel said back smirking while accompanying the younger to the first living room with a hand on his back. As soon as they were sat on the older's couch Yasha got a glass of water for the younger.

"Thank you sir, do you live here alone sir, it looks big" Yuki asked before drinking quickly the water. "I do, my snowflake, I like bigger spaces. So, where were you supposed to go Yuki? You can call me Yasha by the way, don't worry" the older asked still on his feet in front of the younger

"I was looking for my friends' apartment, but I think I came in the wrong place, because, well" Yuki said gesticulating to indicate the apartment. Yasha nodded. "What's his name, maybe I know him, I know a lot of people?" Yasha asked while he poured some whiskey in a glass for himself.

"Pierre, we became friends on uuh Instagram" Yuki said unsure and the other smiled. "What meeting app was it, mh, Grindr?" Yasha asked and Yuki nodded shily making him smile and mess up his hair for the sweetness. "Don't be shy snowflake, I'm gay too, it's normal, wanting to find someone. He lives near here, just the building next to this, you didn't get it so wrong snowflake" the older said smirking before downing his whiskey.

"Why do you call me snowflake?" Yuki asked shily. "Because the original way to write your name means snow, and you're pretty and delicate, so, snowflake" Yasha explained making the other blush.

"It's the first time someone calls me pretty" Yuki admitted and the other looked at him strangely. "They must all be blind to not think you're pretty, snowflake" he exclaimed looking at the younger. "What about Pierre, he didn't call you pretty, snowflake?" Yasha asked genuinely curious. "We never saw each other in face, I didn't want to risk" Yuki answered and Yasha nodded. "You're smart snowflake, you did the right thing" The angel said smiling and ruffling his hair again.

"You like my hair?" Yuki asked and the other nodded. "Yes, I do, they're soft and they suit you well" he answered and the other smiled. "I like yours too, it's rare to see someone so young with white hair but they suit you really well, your black eyes show a lot more" Yuki said and the older blushed this time making the other smile.
"Thanks, No one had ever made compliments about me either" The older said smiling. "Something in common I guess" Yuki said laughing and Yasha laughed too. "Your laugh is beautiful" they said in the same moment, both blushing deeply.

In that moment Yuki looked outside of the glass wall in front of them and saw the sun almost at dawn. "Oh my God, when did it get so late, Pierre is probably so worried" he said panicking a bit. "Time flies when you have fun, eh. Don't worry about Pierre, send him a message, tell him you're okay and if he cares he won't be angry." The angel suggested and Yuki nodded. "Thank  you, I was panicking" The younger thanked before getting his phone and quickly writing a message.

"I think he found someone else to get laid with, he just posted a story with a guy" Yuki said with a bit of sadness in his voice. "I'm sorry my snowflake, he's just an hormonal asshole" Yasha reassured him caressing his back. "Your touch is comfortable, I usually hate people touching me" Yuki said leaning in the touch of the hand. "It's because you're comfortable with me, it makes everything about me comfortable for you" The older said and Yuki nodded, the touch soothing his thoughts.

"Yasha, can I ask you one thing?" He asked with a low voice and the other nodded. "Sure, go ahead snowflake" the older answered still with a hand on the younger's back. "Why are there black feathers on the couch?" Yuki asked shily. Yasha got up and smiled to the younger. "It's time I show you something snowflake, but we have to go on the last floor for this, come" He said holding out his hand to Yuki who grabbed it and got up. Yasha held his hand all the way up to the last floor through all the stairs. On the last floor there was a white room with the same wall of glass with a sight on the city.

"I will need a bit of space my snowflake, stay there" The angel said leaving the younger at the top of the stairs while he went to the centre of the room taking off his shirt. In less than a second his wings were out, black and majestic, enormous but soft looking. "I'm a dark angel, my snowflake, I understand if you want to go away now." Yasha started before being interrupted by Yuki caressing one of his wings. "You make me comfortable, angel or not, and I appreciate it. So I will stay here, wings or not, angel or human" Yuki said keeping to caress the angel's wing. Yasha smiled taking Yuki in his arms before wrapping the wings around both of them.

Yuki made a surprised noise before leaning in the touch. "You know, it's the first time someone touched my wings without me hating it and actually liking the touch" Yasha said with a low voice as the wings were still around them and a higher voice would've hurt their ears. "They're beautiful, honestly. And soft" Yuki said smiling looking up at the older as he was quite taller than him.

Yasha raised his hand and caressed the younger's cheek feeling its softness. "Your skin is soft, I like it" he said keeping on caressing it. Yuki smiled softly looking at the older in the black eyes. "Yasha" Yuki said whispering. "Yes, my snowflake?" The older answered with another whisper. "Can I kiss you?" Yuki asked with a faint blush on his cheeks. Yasha stopped a bit, shocked,  before nodding and leaning to help the shorter kiss him.

As their lips touched they both felt a sparkle go down their backs and they both wrapped their arms around the other's body. Soon their tounges got involved in the kiss before they let go to breath again. "Wow" They said together after a pair of seconds. "The best error I did in my life, I don't think I would've felt that sparkle with Pierre" Yuki said smiling at the older. "My snowflake, it is indeed." Yasha said smiling and looking down to the shorter.

In that moment Yuki's stomach grumbled. "Are you hungry my snowflake?" Yasha asked and the younger nodded shily. Yasha retrieved his wings quickly and Yuki blushed seeing the older's bare body. Yasha picked up his shirt before placing a hand around Yuki's waist and starting to walk. "Let's go eat something"

In two minutes they were on the third floor in the enormous kitchen with the older warming up some ramen he had made for lunch, the top of his body still bare. Yuki was wandering around watching all the pieces of art in the room when he turned to watch the older noticing two big cuts on Yasha's back in the place where his wings sprouted from. He touched them paying attention not to hurt the other. "Do they hurt?" Yuki asked softly and the other shook his head. "No, they don't my snowflake. They actually make it easier for my wings to come out, they never close, but well, it's almost like a tattoo" Yasha explained while turning off the stove. "They look cool, I like them"

Yuki said following the older as he took the two bowls he had put the ramen in to the black marble isle in the middle of the kitchen with an enormous TV in front of it. "Snowflake could you please bring here the chopsticks, they're in the first drawer at the right of the sink." The angel asked and the younger nodded immediately getting two pairs of black metal chopsticks and taking them to the table. They started to eat, between a small talk and the other, talking about Yuki's job as a chef, their favourite colours, the animals the preferred and so on until their bowls were empty and their stomachs full.

After putting the bowls and chopsticks in the dish washer they sat on the couch of the second living room, on the floor right under. "You should sleep here tonight, if you want, obviously, my snowflake, it's late and it's not safe to go home alone at night" Yasha said and Yuki nodded thanking him. "I'm sorry for bothering you" he said shily making Yasha smile. "You're no bother snowflake, come on, I will show you your room" Yasha said.

That night Yuki couldn't sleep, he was in an enormous bedroom with a gigantic bed but he didn't feel comfortable. After starting at the ceiling for an hour he decided to get up and see if Yasha was still awake and, in fact, he was. As he heard the younger knock on the door he smiled. "Come in my beautiful snowflake" He said softly just before the door opened revealing the boy with messy hair and a sleepy face. "I can't sleep" he said making Yasha smiled again for his tired voice. "Come here" the angel said patting the bed near him and the human immediately followed the instructions. He got under the covers near the older felling more comfortable right away. Yasha wrapped his arms around the human who soon fell asleep followed by the angel who kept him warm all night long.

It's safe to say that Yuki never went back home the following day, or the one after for what matters.
They spent their days watching films, chatting and eating on the older's couch. Then, at night, they slept in the older's bedroom, wrapped in eachother's arms.
And it was the best for both of them, until someone disrupted their peace, but that's a story for another day
