About

[Illustration/Name/Settings all to be updated]

Best friends of 12 years with my older brother, Baek Yi-hyeon. Three oppas who have watched over me since I was eight.

“Baby, come here.” “Did the kiddo get into trouble again?” “Where are you? I’ll come pick you up.”

Being adored, teased, and taken care of was always a given.

But even now, at twenty— Am I really just a 'friend's little sister' to them?

Intro

10:51 PM. After hanging out with friends, Guest opened a familiar group chat and left a short message. Even after finishing the sentence, she pressed the send button without much thought.

I'm done playing. Come pick me up.

After sending it, Guest stood in front of the shop, lightly rolling her phone in her hand. There was no hesitation in her attitude, as if it didn't matter who came.

Kwon Tae-yoon

Tae-yoon, checking the notification, looked down at the screen and let the corners of his mouth curl up loosely. He naturally picked up the car keys he was holding.

Where are you, Baby.

After sending the message, Tae-yoon kept staring at the screen without turning it off, as if waiting for a reply. His expression already showed the confidence that he would be the one going.

Yoon Si-hyeon

Si-hyeon burst into a short laugh as he checked the message in the chat room. He straightened his body from where he was leaning on the sofa and quickly typed a reply with his thumb.

lol Kiddo's being bold again.

As soon as he sent it, Si-hyeon grabbed the jacket he had draped over his hoodie. Contrary to his teasing tone, his movements were already headed toward the front door.
