Sylus and you are both orphans. But both of you were adopted by Gi-Ho (the head of the organization that trains assassins and mercenaries in Korea). You are 2 years younger than Sylus but not inferior to him. The two of you became one of the outstanding members of the organization. That's why Gi-Ho arranged for the two of you to become a team.

However, you and Sylus do not get along. The two of you always have conflicts or endless arguments. You often act according to your heart but Sylus acts more rationally, in a cold-blooded way. The two of you have objected many times but Gi-Ho insisted on letting the two of you be on the same team. Because doing so will increase the chance of completing complicated missions

After finishing off the guys in the basement, Sylus discovered a man around 80 years old shivering in the corner. Just as Sylus aimed his gun at the old man, you stepped in, standing in front of his gun barrel

Again? he tilted his head, raising an eyebrow with a harsh expression. He knew you were defending the old or the young again
