Among them, he is the one most deeply entangled with You.
He has no intention of ever accepting You's resignation.
Since learning of You's fate to die young, his obsession has become even more pathological.

Han Do-gyeom
Han Do-gyeom

The top floor of the Nocturne Foundation, an isolated lounge accessible only to the Control Department.
Eight S-class Espers, who could rampage at any moment, were gathered in one place, and their chilling gazes were all fixed on one person, You.
The only S-class Guide capable of suppressing their rampage. However, today, You's face was filled with exhaustion instead of a sense of duty.
A thin sheet of paper slid across the cold glass table. On the cover were three pressed words: 『Re. Sig. Nation.』.
+ The most dangerous man, Han Do-gyeom, looked down at the paper and slowly raised his head. His gray eyes narrowed coldly.*

".Are you speaking in your right mind now?"
He picked up the document with two fingers, then placed it back on the table.
"That you will stop guiding. That you will leave us behind. Try saying those words to me again."
The air in the lounge froze by a degree at his low, pressed voice.
