"Who killed JinZ?" is an ongoing album. Its production is based on Jamuary, and its story is currently being told.

The sun was setting. The tradesmen were leaving the workplace when they saw an unfamiliar motorbike coming into their cabin. Eight men walked out, puzzled. 1 approached the guest asking what they wanted. N said he wanted revenge for his brother. The gang chuckled. 2 laughed that a normal guy and a kid went out of their way there just to hopelessly fight the gang. N smelled the drugs that they used before, he thought he was in for a good time. He told H to find a way to rescue J, and N would take care of the people.

N carefreely walked toward the gang. 3 initiated the fight by punching N's face. The gang had a loud laughter again, ridiculing N. It was then that N remembered how the spirit of fighting felt. Swiftly, N straightened his hand and poked 3 right at his throat, choking him to death in a matter of seconds. The gang no longer laughed. 4 ran into N only to meet a kick to his stomach. The other half of the gang quickly ran back inside their workplace and took some tools to fight. As 4 prepared to stand up and push N in wrath, H rushed into him and kicked him in the nose. While H mercilessly punched 4 to death, N marched forward. 1 and 2 were still in shock. 1 ran into the workplace, calling his boss, whereas 2 fell to the ground. He threw cobblestones into N but was quickly kicked in the balls forcefully. N sat on 2 and was about to finish him. Suddenly, N heard H shouting out. As he looked up, his shoulder was hit by a thrown hammer. J heard a noise outside and screamed for help. 1 knocked on the door, telling J to shut up. Seeing tools in the enemies' hands, N decided to lift 2's unconscious body and ran into the gang. As N went inside, 5 slammed N's head with a plank of metal. N held his head in pain. He kneeled to the ground and the gang thought they had won. But N stood up with one of their beer bottles and charged at 6, who was holding a knife. The force was powerful enough to wreck the bottle. N struck the rest of the bottle onto 5 on his chest. 1 and 7 then tied N's arms together. N then walked backward, pushing the two into a wall. Yet the two hadn't let go. As N was struggling to get out, 8 took another hammer and threw it right into N's face. However, 8 missed and the hammer pieced into the wall. Then H from behind, pushed 8 to the ground. 8 quickly stood up and looked around to see a kid in a boxing stance. 8 laughed and tried to imitate to mock H. H began to jump left and right, which confused 8. 8 then saw H's legs were about to do something so he looked down but was suddenly met with a direct knock in the face. On the other hand, 1 and 7 were high on drugs, their strength would run out eventually. N easily flung them both to the ground. N told H to be quick. N proceeded to grab the hammer from the wall and slaughtered the gang one by one. H tried to destroy the door with his body. Hearing H's voice, J was so delighted that he was in tears. While N was busy, 6 woke up from his pain, took his knife, and scored N in the back. H then went over to help but was hit by a slab from 8. The protagonists were temporarily down. 6 and 8 gazed around and saw their friends dead, they were never angrier. But they were so high on drugs, they no longer had the strength to do anything.

Hearing J's cries, N and H awoke from their stupor. They had trouble standing up. N whispered to H about their plan, urging him to make it work. A vehicle light appeared from a distance. As the automobile approached the location, N instructed H to rapidly finish the rest of the gang. N approached the cabin's entrance and saw R get out of his car. They exchanged greetings for a little while. R, seeing all the corpses, said that he always recruited new members, and N would go down. N slowly took the knife out of his back and threatened R. Suddenly, R pulled out a gun and shot N right in the chest. As N fell to the ground, H stopped moving. He was paralyzed and instantly raised his hands. R entered the cabin and congratulated H. He was astonished at H's determination. R opened the door and grabbed J by the hair. R pointed his gun at the kids. He merely wanted to kidnap J to traumatize him. After a few days, he would let J out. However, R would not have expected such a day. He was talking about his life and L's execution when N from behind shouted out and slit R's throat. R turned around and finished N with a headshot. R wanted to say his last words but H then grabbed the knife and repeatedly stabbed R.
