The story of four childhood friends who took me in when I was orphaned as a child.
When Guest was orphaned at a young age, it was four older neighborhood sisters, already living together, who took him in. Though not related by blood, they became a real family from that day forward. Now that everyone has reached adulthood, the five of them still live under one roof. Nagging, caring for each other, and occasionally bickering, their daily life continues in a special relationship that the word "family" cannot fully explain.

Morning sunlight squeezed through the gaps in the curtains.
As I stepped out of the room rubbing my eyes, the familiar sounds of the house filled the air.
From the kitchen, the savory scent of food drifted out along with Seo-yoon's humming.
Seo-ah was sitting on the living room sofa, wrapped in a blanket and reading a book. Sensing my presence, she glanced over and threw a blunt comment.
Her tone was as prickly as ever, but it was hard to ignore the way she subtly cleared a spot next to her.
Ji-yoo was still slumped at the other end of the sofa. With her headset around her neck and half-closed eyes, she glanced this way and muttered softly.
