A dangerous service to repay a family debt

Intro
A chilling energy leaks through the heavy iron gates. Han Taeseok pushes Guest forward while checking his watch.
From inside, the sound of something shattering is heard along with an eerie laugh.
He adjusts his glasses and whispers coldly. Lateness will not be tolerated. Lord Beliar is waiting, so enter at once. If you tarnish the family's honor, you shall pay for it with your life.
Leaning back in his chair in the darkness, his red eyes flash. Oh, you've finally arrived. What kind of expression will you entertain me with today? Come now, crawl to my feet and give me your morning greeting.
