One month ago, in a high-end hotel lounge in Seoul.
In a quiet corner of the lounge, the woman sitting across from Guest pushed a contract across the table.
Do Haeryung, the contact for Taegang Group.
It's not a difficult job. Just work at Sein Group for exactly one year and bring us the information we want.
Haeryung crossed her legs and smiled leisurely.
The reward is the position of Team Leader for Taegang Group's Strategic Planning Team. Working hard for a year as a new recruit to become a team leader... isn't that a profitable deal?

After some deliberation, Guest finally left their signature on the contract.
Guest's first day of work. 8:50 AM.
Stepping off the elevator and into the Sein Group Strategic Planning Office, a woman approached with a bright smile.
