A/N: This is my first time writing, so sorry if it's not perfect! I tried to make it fluffy! I understand that not everything in here is factually correct in the manga, so sorry! Please comment and stuff, I'm a newbie to writing and really need all the help I can get! Thanks c:
"Alright Flareon, use fire spin!" Red was in Viridian Forest, helping his recently acquired eevee get used to its genetically modified body. Team Rocket had once captured it and experimented on it until it could change from eevee to Vaporeon, Jolteon, and Flareon, and back to Eevee. Red wasn't sure what to do with it, but for now he figured he would help it try to get as used to its body as possible. Suddenly, something rustled off to the left. Red froze and stared, looking for signs of danger. He was pleasantly surprised when an Oddish popped out of a nearby bush. It calmly waddled by Flareon, and suddenly Flareon was covered in a strange dust. As the oddish fled, Red realized they must've been disturbing the oddish with their training, so it used stun spore on Flareon.
"Flareon, you’ve been paralyzed! Sorry, I’ll have to be more careful next time. I’ll get you help right away." Then, things got worse. It had been a lovely, cloudless day, until all of a sudden the skies were filled with gray clouds above and rain shortly followed. Within a minute, Red's hat and clothes were sopping wet.
"Great. Jusssst great." He'd already been out for an hour, and had no idea how long it would take him to get back. He knew he had to get Flareon the help it needed, too. To add to his current situation, he could hear faint rumbling in the distance. “I can't stay outside if this is going to turn into a thunderstorm,” he mumbled to himself. He began weaving his way through the trees until he found a slightly beat up path. He followed it, careful to stay on track, and found himself before a small cottage. The small wooden sign that stood before it had writing on it. He squinted and made out "Yellow of Viridian Forest." He approached the door, and hesitated.
"I guess I lucked out on this one. I must look like crap, but I don't have much of a choice," he muttered. He knocked on the door. A moment later, it opened to reveal a short, green-eyed girl with blond hair cascading down her shoulders.
"Red!" She exclaimed, her eyes wide.
"Heeey Yellow..." he replied sheepishly, self conscious of his appearance and feeling a bit embarrassed for intruding on her.
"Come inside! You must be freezing! Stay here, I'll get you a towel!" She rushed off, leaving Red smirking at her concern. He had to admit, she really was adorable. He blushed at the thought. Although he knew he had feelings for Yellow, he still wasn't sure what they were yet. Yellow returned with a towel, which Red gratefully accepted.
"I'm so sorry I don't have anything for you to change into! That is, unless you want to wear my clothes, but I somehow I get the feeling you don't..." Red grinned.
"I appreciate the offer, but I think I'll survive. It's enough for me that you even bothered to let me in."
"Of course I let you in, why wouldn't I?! You could've gotten sick out there!"
"You're so cute, Yellow," Red thought. When he saw her blush and look away, he realized with a start he'd said that out loud.
"I mean, you're always so concerned about other people. You're a selfless girl, and I'm glad I wound up at your place rather than Green's. He'd of probably just shut the door in my face," Red tried to recover. Yellow smiled.
"He wouldn't do that. I'm sure there's a heart somewhere in that chest of his. It just may or may not be covered in a layer of ice or something," she giggled. "But you know you're welcome here anytime!" They smiled at each other, and then both looked away, blushing.
