So, as the title implies, this is my first Oneshot I've ever made. Please don't expect it to be mind blowing, as I'm still below the level of an amateur. But, still, Happy Reading!

Love is a Many Evolving Thing

"Wow, Derek, today has just been the best day ever.", Evan said. "Yeah, and I'm glad I got to spend it with you." "Oh, you can be quite the touching Deino, you know that?" "Well, you can be quite the naive Eevee, you know that?" They started laughing, before their eyes met. "You know, when I'm with you, I feel like I'm not dying from Pokérus. I feel on top of the world." "Well, I could elevate you even higher.", Derek said, before kissing Evan on the mouth.

She returned the kiss, and while doing so, started to glow. Evan's tail got thinner and shorter, the scruff around her neck disappeared, and bows formed around her right ear and neck, that generated ribbons. When they stopped, Derek grabbed a mirror he prepared and showed Evan what happened. "Yes, I'm finally a Sylveon! Thank you, Derek!", Evan said. Derek wasn't listening, as he was walking away from her.

"Derek? Where are you going?", Evan asked, snaring his ankle with a ribbon. "Evan, let go of me. My work is done, you don't need me anymore. You don't need a Dark Dragon type Pokémon like me." "Derek, what are you saying?" "Evan, I took you on this amazing day because I had a sibling who was in the same position as you, but his final days were filled with pain and regret." Tears started coming into his eyes.

"When I heard about your condition, I swore that I would prevent that from happening to you. And now, the final step is complete. I was told that you wanted to become a Sylveon, so I planned that last moment so that you could evolve. Now that my work is done, you don't need a Dark and Dragon type like me."

"Yes, I do! Derek, I don't care if I might severely hurt you, I want to be with you! You've made me happier then I've ever been before, and I want you to keep me that way! Please don't leave me, because if you do, my last days will be filled with pain and regret, like you were trying to prevent!" Evan was laying on the ground, crying now, thinking that Derek had left her, ignoring her pleas to stay. But, as she was crying, she felt a scaly hand touch her paw. She looked up, and saw Derek looking at her. He just smiled and helped her up.

"You really are quite the naive Sylveon, aren't you?"
