I was staying over at my best friend's house for half of the break. Her parents were away on an anniversary trip, leaving us and her step-sister alone in their residence.

I had only come across her step-sister once during a sleepover, and that's all I could recall besides her name starting with "R." To be fair, she was an attractive girl, with features that were completely different from my friend's, but still, she was Korean.

My best friend, Yeji, has never told me much about her, and I don't know why. She doesn't even want me near her.

Perhaps she's a complete dick or a ruthless flirt.

One morning, I found out and talked to her.

My friend was brushing her teeth upstairs while I ran to the kitchen to grab a glass of water.

Unexpectedly, the sister appeared behind me, obnoxiously drinking milk.

I jump, coming near to dropping the cup on the floor and creating a hazardous mess. "Holy— What the hell?" I step backward, and she counters with an approach.

She takes a big gulp and places the glass on the counter. "What's up? What are you doing in my kitchen?"

I was completely distracted by her ridiculous milk mustache that I had to ponder what she asked me.

"Uh... I'm—I'm getting some water?" I answer, raising an eyebrow as I face her intimidation.

"Are you Yeji's friend?"

I present her a warm smile, signaling I mean no harm. "Oh, yeah. I guess we haven't really met..." I chuckled nervously.

She lowers her voice and narrows her eyelids, a suspicious look suddenly adorning her. "Who are you?"

"Um, do you mean my name?"

"Yeah."

I couldn't tell if she was fucking with me or an actual dipshit.

"(Y/N). My name is (Y/N)."

"Cool." She turns around to strut away.

I raise my voice and shriek before she vanishes. "And yours?!"

"I'll tell you when you need it."

"Bitch," I mutter under my breath, gathering myself to confront Yeji about her behavior.

I headed upstairs and barged into Yeji's bedroom to witness her in the middle of changing, and I couldn't care less.

"What's your sister's problem?" I bark and dive onto her mattress, pulling out my phone to scroll through the weather with.

She twists her neck, widens her eyes, and lifts her eyebrows, creasing her face. "Fuck, did you talk to her?"

"Yeah. I came across her in the kitchen, and she was just being weird. Kind of rude, actually," I add.

She sulks to display her outright disappointment. "Sorry. That's why I don't want her near you. I just feel like she'll ruin things."

I sigh, absorbing relief out of the composure I maintain around people like her. "It's fine."

"She's not even my real sister." Yeji walks toward the bed and gets comfortable beside me. "That fucker almost feels like she's just a stranger who lives here."

"How old is she?"

"She's... 20-something. No job, no school, nothing. My step-mom thinks she's still a kid. Can you believe that?" Yeji rolls her eyes in disbelief.
