So this one needs a little bit of context haha, I don't tend to write those snippets out of blue, I tend to write them when I talk with my fellow Kyusung shippers haha, and for this one we had this idea of Yesung as a Lamia, so for people who might not know, a Lamia is a half-snake/half-human creature, and Kyuhyun as an adventurer. The world they are evolving in, is a bit those worlds where leveling up is actually possible like in the real world haha. The premise of it was basically: Adventurer Kyuhyun finds an injured Lamia, and instead of killing it, decided to save him. Shenanigans happen, they fell in love, etc., and Yesung finally levels up after a while, and this is what the snippets talks about haha;

So please enjoy!

"[...] And Kyu looked at his beautiful boyfriend worryingly, he wasn't sure what was happening, he only knew he was suffering. He didn't understand why, leveling up for humans was a painless thing, was it that different for monsters?

"Kyu, my tail... It hurts" he could only hear the pitiful moans of the man (?) he loved while taking his hands trying to sooth him with well intended, but in the end useless words, Kyuhyun could only be frustrated at his own uselessness.

"Is it always like this?" He murmured into his ears, "is it always that painful?" 

Yesung hesitated at those words, he was sweating, and his whole being was changing, he knew but, not yet, he couldn't tell Kyuhyun yet, not until it happened.

"No... But" he paused "I wished for something, at my level, we can-argh!" he moaned in pain, and Kyu instantly shushed him, telling him to not exhaust himself.

And then suddenly, Yesung screamed and light started to envelop the cave, Kyuhyun got scared for his boyfriend, so his embrace tightened a bit more around Yesung, the light blinded him so he naturally close them down.

When he opened them again, Yesung stopped screaming and was only panting. But instead of relief, it's not what got his attention.

No, it was the pair of smooth looking legs just in front of him instead of the tail that Yesung usually had. He stared.

And stared.

And stared.

And stared again.

Yesung looked a bit shy, especially at Kyuhyun's expression, he didn't know how his boyfriend would react at this.

"When we reach a certain level, Lamias can evolve into two different things" he started, "my wish was." he got a bit shy," my wish was to be able to love you openly in your world as well, I want... I want to meet your friends and family, I want to see the beauty of human towns with you....I want to be part of your world too, not only you to be in mine."

Kyuhyun looked softly at his boyfriend, who was still in his arms, and kissed him softly at those words.

"No matter what, you'll always be part of my world, even with a gigantic snake's tail and scales" He said. 

He then looked back at those legs and couldn't keep himself from touching them, Yesung moaned softly. Kyuhyun stopped instantly.

"I'm not used to it yet, it's so weird" he said while moving his feet slowly, he frowned. "I don't think I can walk yet."

Kyuhyun chuckled at his annoyed expression.

"It's alright" Kyuhyun said.

"I can carry you until you get used to it."
