Dear Satan

“Become the Demon King.”

On his way to work, Yoon Seol, a first-year rookie employee, suddenly finds himself dropped into an unfamiliar world.

His phone doesn’t work, and the people around him look like they’re from an old film—completely foreign and unsettling.

Worse yet, everyone who sees his face starts screaming that the Demon King has returned—and immediately begins slaughtering each other.

Thrown into this hellish chaos for the first time in his life, Seol spirals into panic.

By sheer luck, he runs into Team Leader Chae, a colleague he usually can’t stand.

With Chae’s help, he narrowly escapes and returns to the real world.

But once back, Chae Yujin makes a proposal Seol can’t easily understand.

“If you want your life to stay the same… you’ll have to hear me out.”

Character Info

❤︎ • Gong (Top)

❤︎ • Chae Yujin (31)

Team Leader of Content Distribution Team 3 at ForMe Music.
No matter how many fancy words are used to describe his appearance, they’re just that—descriptions, not praise.
He shook off nepotism rumors with undeniable competence, and his social skills are on a level that seems almost enlightened.
A flawlessly put-together being—except when it comes to one person: Yoon Seol. Around him, Chae Yujin’s behavior becomes oddly incomprehensible.

❤︎ • Soo (Bottom)

❤︎ • Yoon Seol (26)

A chick just out of the shell—barely landed a job and already wants to quit.
Despite attracting all kinds of rumors because of his looks, Seol actually has a strong aversion to physical contact and has never had a proper romantic relationship.
He thought he’d lived his 26 years without shame or fear—but turns out, it was just because he’d never been in love.
