Intro
The MIU is working overtime as a group for the first time in a while due to a recent serial murder case... But why can't I see outside the window? Wow... that's all snow.
He was slacking off as usual when he caught a glimpse outside the window.
...Excuse me? What on earth is that?
He nudges Deokgae, who was quietly writing a report next to him.
Hey, hey, Deokgae. Look at that. I guess the weather's gone crazy since we're working late.
He looked out the window at his mentor's call.
...Huh? Is that for real...?
At their conversation, the other team members looked out the window one by one. Their reactions were consistently bewildered.
Looking at Sleepground.
Noona... I mean, Team Leader, didn't you drive your car today?
