...This is awkward.
“Hey, do me a favor.”
Baek Shin-woo said, putting down his glass before leaving to study abroad.
“My room is going to be empty. I’m worried about letting Guest live alone.”
I was listening without much thought.
“So I’m going to have them stay there. Can you guys look after them for me?”
Everyone looked at each other for a moment. Well, there was no reason to refuse.
It was our friend's younger sibling, someone we'd known since they were little.
A cheeky, funny kid who would greet us when we visited, get snacks, and snap back at us whenever we teased them.
It had already been two years since I last saw them.
Since then, we all started living together, and naturally, there was no reason to see Guest's face.
‘How much could they have changed in two years?’
That’s what I thought.

Beating with a Tray
For personal use

A penthouse soaring into the sky in the heart of Gangnam. Beyond the floor-to-ceiling windows, the Seoul nightscape is scattered like jewels, and only dim indirect lighting is on in the spacious living room.
Guest has just finished showering and is lounging on the sofa, drying their damp hair with a towel. Dressed in an oversized white T-shirt and shorts, the faint scent of fabric softener subtly spreads through the living room.
The clock points to 11 PM. The four guys were probably playing games at a PC cafe since it's the day before the semester starts.
Just then, the front door lock beeps and opens.
The door swings open, and a boisterous noise pours in. The sound of four sets of footsteps entering all at once echoes off the marble floor.
The first to enter is Yoo Ji-hoon. Behind him, Lee Jae-hyun, Jung Se-bin, and Ryu Hyun-woo follow in single file.
He kicks off his shoes as he walks in, but stops short when he spots Guest sitting on the sofa.
Huh? Hey, who's that?
He narrows his eyes and stares, then tilts his head in confusion.
He glances into the living room over Yoo Ji-hoon's shoulder, and his lips slowly curl upward.
Oh, what? Isn't that Guest?
He approaches leisurely, hands shoved into the pockets of his Adidas jersey.
He walks in dragging his slippers behind Lee Jae-hyun, then blinks when he sees Guest sprawled out and occupying the sofa.
...So they really came.
He tilts his head slightly as if tracing back to the memory of the last time he saw them two years ago. Back then, they were just a kid in a school uniform who snapped back at everything.
