Interpersonal Relationship

Trust

(Inside of NSS agency)

The NSS organization is a South Korean National Security System secret organization that defeats enemy that are threats to the country. It is a very secret organization that even both Hyun-Jun and Sa-woo were warned before entering the agency that one cannot trust or depend on anyone else in the organization team, even best friends.

Sa-woo who got an order from the NSS to get rid of Hyun-Jun, he eventually didn’t keep his own trust to Hyun-Jun.

Sun-Hwa, in another case, trusted her own country, North Korea, that they will keep her mother and her siblings alive, but her trust to NK fails as she hears that her family has been murdered. She confirms her family's death by phone calling with her boss, Chul-Young.

During her chasing of Hyun-Jun, she realizes that there is no reason to return back to her own country, so she sides with Hyun-Jun at that point.

Justice

(NSS group meeting)

NSS organization exists to serve its own country; so, obviously, the workers of that organization devote everything into their assigned missions.

Sa-woo, who has been ordered from the organization, feels that he has to fulfill his mission of killing his best friend to keep his justice.

Hyun-Jun and Sa-woo have been best friends since their training at the Special Force before becoming NSS agents.


Hyun-Jun and Sa-woo relates to each other with great friendship, but Seung-Hee, whom both of them falls in love with, comes into their lives. This causes their friendship to split gradually. Hyun-Jun and Sa-Woo are not aware of each other's feelings toward Seung-Hee growing.

But when Sa-woo finally realizes that Hyun-Jun and Seung-Hee are lovers and they both have mutual feelings to each other, he keeps his own feelings to himself. However, as he starts to think that Hyun-Jun has everything, Sa-Woo gradually distances himself from his friend.

Betrayal

(Sa-Woo pointing gun at Hyun-Jun)

As the main theme introduced “betrayal” by Sa-woo to his best friend Hyun-Jun, this betrayal was caused by lack of trust, strong justice, and split of friendship. Another cause also included was threat from NSS that Seung-Hee will also be exiled from NSS and Sa-woo, not wanting this since he still has feelings for Seung-Hee and wanting to protect her, follows the order right away.

His betrayal to Hyun-Jun later leads to guiltiness since he sees how Seung-Hee is breaking down after Hyun-Jun’s death. Then when he comes to know that Hyun-Jun is alive, he feels that he doesn’t have any gut to face his friend, whom he betrayed.
