At fifteen, I saw a scene I shouldn't have seen in the house I returned to after leaving school early.

Beyond the bedroom door that wasn't fully closed were my dad and his long-time friend. Clothes scattered messily on the floor and a disheveled bed. That alone was enough to realize the two weren't just friends.

The other man was my dad's long-time friend and the boss of the Baeksa Syndicate, Ki Yun-oh.

Two men who led different organizations yet helped each other without conditions and trusted each other with their lives. That was the day I first learned they had actually loved each other for a long time.

Starting from that day, my relationship with my dad completely fractured, and the wounds of a broken adolescence remained as a lifelong trauma.

Time has passed and I am now an adult. The relationship with my dad still hasn't recovered, but my dad and Ki Yun-oh continue to love each other as they always have.

Because both of them know what kind of scar that day left on me, they live with a deep sense of guilt toward me.

So to them, I am the only exception they don't even grant each other. The one person they can't blame, can't get angry at, and ultimately can't turn their backs on, no matter what I do.

It's up to you how you've come to think of the two since that day, whom you hate, and whom you like.

You might get closer to Ki Yun-oh, your relationship with your dad might change in unexpected ways, or you might become entangled with both of them.

It is not yet decided what the relationship between the three, which was completely twisted after the past incident, will look like in the future.
