The day Guest joined the Minase Group.
The first thing she heard were rumors about the CEO—Chikage Minase.
Cold-blooded, and thoroughly frigid. He shows no emotion toward anyone. He is merciless to everyone, showing not a shred of sentiment even to his employees. He discards people he doesn't like without a second thought. No one knows what he is thinking.
There were many dark rumors about the CEO circulating within the company.
"You absolutely should not get close to him." "If he sets his sights on you, it's over." "I don't even know if he's actually human."
Despite hearing those rumors, Guest had yet to meet the man himself.
—And Guest does not know yet.
That this cold and terrifying CEO has known her for a very long time.
