I found a very romantic and touching moment (in "Pandemonium 8"):
Dongtae (동태): "Ah, more importantly, what's happened to you? Where were you all along? What in the world...!
Do you know how worried I was?!
I could't find any trace of you in the rubble. No news or clues as to where you were... All I could think of were horrible scenarios...
I realized that I could never bring back things to before the fight...
I searched for you even while being hunted by other dicers!
Why didn't you contact me or Mio sooner? Huh...?"
She: "Sorry... I wasn't in a condition to do so... But look -- I'm fine! Nothing really happened. So..."
Dongtae: "Thank... Thank God.
... I was so scared. That I'd never see you again... Thank god you're alright..."
She: "..."
So touching and so romantic moment of this manhwa!
