The last chapter was what happened in the past of the mc. Basically it shows how the mc entered the company and became part of the idol group and it shows that his band mate( the older one with white? hair) became addicted and then when he went to get the guy out of the drugs the guy force fed him the drug that made him unable to feel happiness.
The MC has PTSD because of a drug called “Happy” (correct me if I’m wrong). Then, the ML starts investigating who created and distributed the drug from Brazil to South Korea. At the same time, he is also trying to find the suspect responsible for the MC’s current condition, where he became afraid of lights and could no longer perform on stage with his former groupmates. That’s all I can remember. And now we know, in this new chapter, who is the responsible suspect for making the MC acts like that (tbh, this update is enough to understand the rest plot in the future)
Can someone explain to me the plot up to the newest chapter bc I’m so confused. D
