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

As school started, H was surprised that J didn't arrive. H knew that despite being lazy, J would never miss a class, even in bad conditions. H texted J in a joking tone if he forgot to wake up. But then, H didn't receive any reply until the class ended. J hadn't been online since morning either. He walked out of the classroom, confused. H tried to call J through social media but failed. H attempted to call J via phone number before he decided to go to J's house.

H greeted and asked how J was. Only to hear the deep voice of R. R mocked H to come there and save his friend, thinking that H didn't know the location. H was in denial, he didn't think things could escalate that quickly. H then yelled at R if he ever did anything harmful to J, H wouldn't take it easy. R laughed out loud and let H listen to J screaming for help. R then talked about L's demise which made H gasp loudly. He knew that he must take action immediately.

H tried to call the police but due to the peculiar nature of the event and his being a minor, the police thought it was a prank. As he thought about talking to his and J's parents, he remembered L's brother. Thinking that it was more important to inform N about his deceased brother, H decided to look for N's number and call it. After a moment, N answered the call. H was sorry to inform N about the situation. Whereas N had already anticipated this possibility. In a shaky voice, he told H to meet up around the afternoon.

Later, N and H met at a small coffee shop, where N usually relaxed. They started by exchanging names and basic information. H couldn't recall the particular place, but once he mentioned the town, N realized who was behind it all. As eager as H was, N advised him not to worry. N understood that RGB wouldn't kill without proper motivation. He believed L must have been involved in something huge to meet such a tragic fate. As for H's friend, if R wanted H to come then he had no intention to kill. H wondered how N could be so sure of all of those assumptions. N introduced himself as a local chef and a renounced gang leader. H at this point started sweating. N went on to say that his group and RGB had previously been rivals. Unfortunately, the police discovered N's gang operations, and they were condemned to years in prison. N came out last year. Then N asked about H's information. H was an intermediate boxer. He was willing to save J. H added that his mom was a lawyer. That gave N a great idea.
