Kyle's mother was nice, and understanding, growing up around her gave Stan some comfort and a moral compass of black and white, what was wrong and what was right. 

She was stern and he thought she was so mean sometimes, but she just cared a lot about the people in her life, at least that's how Stan would've described her to (y/n) when she asked about her, while they were going to visit Kyle and his mother.

(y/n) noticed how it didn't feel like home, how disconnected Kyle and Stan were from each other, the atmosphere felt so cold. She watched how Stan grew a giant grin while walking up to wrap his arms around Sheila, picking her up to twirl her, and how she laughed, patted his back, "Oh put me down, ye sap" and he did. 

She stared at him so carefully, noticing the scar across his face, she cupped and held his face close, "What on earth happened to you?" Stan smiled at her, thinking for a second before answering with a little sarcasm, "I tripped" This would have been a reason that he gave to her all the time when he was growing up, and when she'd patch Kyle and him up after getting into some trouble. 

She was the closest thing he had to a mother. Sheila shook her head, licking the tip of her thumb before rubbing it against his cheek to wipe off the dirt "You are always gettin' into some kind of trouble" and Stan tried to shake his head to get away from her hand a little, ".. You'll embarrass me, momma" in a little voice that made (y/n) smile, Sheila caught a glimpse of (y/n) from the corner of her eye and stopped to look at her, "Who's your new friend?" 

The sudden attention made (y/n) stiffen a little and feel a little nervous, Sheila didn't know what to expect from her, usually, the girls that Stan liked enough to bring home were pretty, but not very smart or had very good manners, maybe even little slutty, and Stan turned to brighten his smile towards (y/n), ".. That's (full name)" 

(y/n)'s smile grew a little shy, lifting her hand from how she folded them in front of her to push hair behind her ear, ".. You can call me (nickname) if you'd like to, ma'am" Her tone was so soft-spoken and gentle, Sheila stared at her. She found (y/n) to be charming, so delicate, and smooth, she thought (y/n) balanced Stan out well from first glance, nodding her head, "I'd like to.. and you can call me Sheila.. if you'd like to" watching (y/n)'s shy smile grow a little more comfortable, bringing her hand back, she nodded her head.

When walking into the hour, (y/n) stepped onto the stairs with the help of Stan's hand, he rubbed her knuckles with his thumb gently, and when she got a little close to him, he leaned down to speak lowly to her through a teasing smile while he mimicked her words, ".. If you'd like to, ma'am" and watching her expression flatten while keeping her smile that shifted into annoyance, he added teasingly towards her, "You're so cute" his tone increasing in pitch. (y/n) shook her head at him, pulling her hand away before grasping her skirt and walking ahead. 

Stan couldn't help but let out a gently laugh through his nose while he watched her walk ahead of him into the house, shifting his gaze towards Kyle who leaned against a wooden post with his arms crossed, his expression made Stan's smile fade completely, watching how Kyle pushed himself off the post and walked into the house. 

It felt cold, Stan could feel a shiver go down his spine before going into the home, he hoped this visit wouldn't seem so daunting once it got started.

It was harder for Kyle to accept Stan because he couldn't get past the way things happened. But Sheila did because when Stan told her what happened, with tears in his eyes and on his knees in front of her, absolutely crushed by what happened and filled with regret, she felt so much pain and felt so much pity at the fact that Stan was still just a scared kid.

Kyle didn't understand that at all.

The interior design of the house was homely, with pictures and green plaid. There was an old wooden piano, a bookshelf, and a fireplace. It was pretty. " You have a beautiful home," (y/n) spoke gently while her eyes roamed the home, scanning the family photos on the wall. How happy they seemed—two boys, a husband, and a wife—it seemed nice.

She assumed one of the boys, who was smaller and younger, had moved to another town and had an entirely different life that he created for himself. (y/n) She didn't think much of it at the time.

 Sheila smiled, "Thank you"pausing to stare at her, her gaze following towards Stan. He took off his hat, and Kyle who stood near him, remembered the height difference they had when they were just kids, so strange what time can do, ".. would y'all like a drink?.. some beer?" 

And (y/n) caught a glance at Stan's growing smile, she shook her head, there was no way that she was ever going to drink again, especially around him, ".. Nothing for me, thank you" Huge bummer, Stan lifted his hand to mask his teasing smile by feeling his bottom lip with his index finger, pressing his hat to his chest, ".. I'll take a beer" She has never had alcohol before meeting him, and after everything, when they finally got together, she had a drink here and there but never all the time, very sparse drinking habits, though he always hoped that she'd pick up drinking more often since she always got so kissy and clingy with him, always tuckered her little self out, Stan thought it was so cute and so so so hot.

It got quiet while Stan sat on the leather couch, with his leg resting over his knee, his beer in one hand while he carefully watched (y/n) stand and take in more of the room, Kyle sat two seats away, it felt tense but he tried to make conversation, ".. Do you... remember that corner store where that old man slept at the counter?" 

And Kyle thought for a moment, before answering with a question, ".. Old man Will?" Carefully studying how Stan tried to remember the name before nodding his head, ".. yeah.." he let it grow silent again before Kyle asked, "What about it?" Stan didn't think talking to him was this hard, ever, in the entire time that he'd spent talking to him, it was almost unbearable, ".. Just.. how much fun it was.. to steal a beer from the store and hide.." his voice got so quiet like it was a forbidden topic, a detail that shouldn't have been mentioned or shared.

".. The three of us.." pausing for a second to raise his tone a little, like he wanted to skim over it, not talk about that detail any more than he had to, "Taking turns trying it" 

Deafening quiet again, before Kyle said almost bitterly, ".. I remember how you pushed us to do that.. even when he didn't want to" Unapologetic and loudly criticizing the past, his tone laced with regret and distaste towards the memory, it made Stan wince a little, gently, trying not to bring attention to the physical reaction to the harshness of his words, it was so difficult for them to connect again even when he tried so hard.

(y/n) could feel the tension growing and laying in the atmosphere thick and suffocating, studying how Kyle's words acted like whips and lashes, cutting right through Stan, and how it grew increasingly uncomfortable and quiet between them. 

She rested her hand on one of the shelves of the bookshelf, thinking, trying to create a little space between them with some mindless detail about herself, ".. I used to.." her words faltering a little when their eyes focused on her, continuing a little more loud and sure of herself, ".. Read in this treehouse... I would hide from my daddy to avoid doing my chores" 

Kyle's eyes seemed disinterested in her detail of herself, but Stan grew more interested in what she had to say than anything else, he liked knowing things about her, it'd put him at ease quickly and easily, he started to smile, ".. Well, I didn't know you were a regular rabble-rouser, sweetheart" 

(y/n) smiled, nodding her head, her hand traveling a little across the shelf, ".. mhm.." she hummed, squinting her eyes gently and playfully towards him. ".. I just hated those dishes" which made Stan laugh, shake his head her, she was so funny, he started to feel glad that she was there with him, she was exactly like a fresh breath of air. 

And Kyle stayed stoic, standing up with a little mutter, ".. I'm going to see if she needs any help" It was hard to be around Stan, how he could laugh and smile, it didn't feel fair. 

Stan's laugh died down into a soft smile while he watched him disappear into the kitchen, letting it grow quiet again, he didn't know what to say so he took a small sip from his beer bottle. (y/n) stared at him, filling her lungs with air and gently letting it out while she looked away, following her hand towards the wooden piano, feeling the delicate details carved into the top that hide the keys, ".. tough crowd" she muttered a little.

Stan watched her, nodding his head with a gentle, ".. Yeah"

it was so quiet again, but more comfortable between them, he had a feeling she wanted to ask him who the third person was, why it seemed to create a rift between Kyle and him, but she didn't know how to ask, and Stan didn't know how to answer. 

Instead, he shifted the conversation a little: ".. You play?" he studied how she lifted the cover to reveal the piano keys, how she shook her head, which made her hair fall forward a little, and how she lifted her free hand to push hair behind her ear. She was so pretty beside a wooden piano like that. "No, I wish I did, though," he said, pressing a finger on one of the keys to let out a single note.

This is all that I wrote. If this gets more love, I'll try to wrap things up, but idk yet. 

Here are my plans if someone wants to pick this up and run with it in rps: 

Stan playing the piano and getting behind her, pressing his back against hers while teaching/showing her how to play piano. 

(y/n) finding out through a massive blowout between Kyle and Stan that this mystery third person was Ike. Ike died in this Wild West environment, most likely because Stan got into trouble with the wrong groups of people. 

Kenny is a wild cowboy and still chasing after money and women. Stan and (y/n) get stuck in Kenny's town, and Stan slowly returns to his old habits. Resulting in them getting stuck there for a few weeks, maybe even a month. (y/n) giving Stan a reality check, maybe leaving him in that town ("To hell with you, Stan Marsh") and Stan finding her later on. (maybe (y/n) gets kidnaps? Stan rescues her, and she gets all pouty and angry at him, maybe she cries) 

(y/n) and Stan finally gets to her hometown. There's music, food, a campfire. A very welcoming and open environment, a real home. Stan gets jealous over (y/n) when Clyde dances with her, holds her close to him, and is romantic with her because he waited for her. 

(y/n) gives Stan a haircut, it's very sensual and romantic. 

Stan finds out about the (lack of) money ("Missy, you are a liar! You..." *finding his words* "You... You scammed me with yer perty eyes!") There can be some tension between them, but I always imagined it to be more comedic during this time because Stan found it hard to get mad at (y/n).

Cartman is the leader of the red-horned bandits, another old friend of Stan's, especially when he was traveling in a dark place when his father died. Stan and Cartman settle things in a shooting, cowboy style, quickest draw. There's some humanity in their friendship and this ending. 

Then the whole classic, "you're leaving?" scene in any cowboy movie. And (y/n) kisses Stan. 

Happy ending, and a blowjob in a horse stable, a lot of sex. You can even extend it into marriage, and kids, and I always imagined Stan building a house for (y/n), her father not liking Stan etc. 

The end, unless you guys want me to write these scenes for you :)
