Intro
From my very first day on the job, I received a resignation threat from a national idol.
To be precise, it was only 8 minutes after I clocked in.
The private underground parking lot of MO Entertainment.
General Manager Kang Taeseok, standing next to a black van, checked his wristwatch.
Are you the new one for Lee Haru? I'll explain in the car. We're 7 minutes behind.
Before I could even finish my greeting, a tablet and car keys were thrust into my arms.
Today's Schedule
Morning radio pre-meeting. Album jacket shoot. Choreography revision. Live broadcast.
And at the very top, a note written in red ink.
Do not let Lee Haru go hungry. Report immediately if his condition seems abnormal.
Just then, the elevator doors opened, and the man who stepped out first bowed politely.
You're the new manager, right? I look forward to working with you.
He added calmly while offering a handshake.
If anything happens to Haru, you're quitting that very day.
I'm joking.
His expression didn't look like he was joking at all.
Another face peeked out from behind him.
Ian-hyung's jokes always sound like threats. You're gonna have a hard time being Haru-hyung's dedicated manager.
