Samdak defending Hobin and Hye-yeon
Gaeul is leaving with a bunch of snacks when her father asks if she's sneaking off to see Hobin. Gaeul asks him why he's being so defensive about her, and if it has to do with that incident from his past. He is taken aback. She tells him that she doesn't care what happened, but it is a lot more irresponsible to not do anything about it. Samdak later finds Hobin being attacked by 244's men with a syringe, and he grabs the syringe with his wallet. He defeats all the men and tells Hobin that he took some time to think about his offer. After watching his videos, he decided to turn Hobin into a human weapon.[13]
It is 85 days until the drug boat is to land in Korea, and Samdak is training Hobin. Samdak tells Hobin that his moves weren't meant for his physique, and that it is amazing he made it this far with the videos. Hobin wonders why they are training in the middle of a park of all places. A passerby thanks Samdak for teaching her some breathing techniques, and there is a sign in the park offering martial art lessons from a man who has travelled 100 countries. Samdak asks Hobin to punch him, but Hobin is blown back by his strength. He tells him to repeat 100 times.[14] When Samdak tells Hobin his training is finally over, Hobin doesn't believe it. He chucks his phone aside and Hobin catches it perfectly. Samdak tells Hobin that with a body like that, he won't be losing to anyone ever again.[15]
Samdak appears before Nameless and the Soo trio as they are trying to help Hobin film the event.[16]Nameless tells Samdak that he's heard much about him from his days as an army operative. He was one of the few men with a liscence to kill, and people used to talk about him. Samdak tells the man he can't understand what he's saying, since his English is rusty. The man pulls a gun on him and Samdak asks if he would like to see the final episode from his playlist: How to Win Against a Gun.
Nameless shoots and Samdak grabs his arm to redirect the bullet. He manages to wrest the gun away from him before ripping a piece off. Samdak recognizes the nameless man as a former member of his squad in the army. The nameless man rushes at him with a curved knife, but Samdak flips him over and he lands on his head. He tells him that winning against knives and guns is bullshit, and only the strongest wins in the end.[17]
