You can find up to chapter 392 on here if your phone or web browser has an auto translate feature: https://booktoki466.com/novel/9663195?stx=%EB%A7%89%EB%82%B4&book=%EC%9D%BC%EB%B0%98%EC%86%8C%EC%84%A4
Also, there are 3 out of order chapters between 147-200.
The rest of the chapters can be bought super cheap on naver's korean series app using Google play or the iPhone app store's e-payment. Then, I Google translated the chapters using naver series on my PC.
Spoiler
Based on the novel, each member has their own set of either fake scandals or personal/health issues that end up getting leaked into the public.
For Siwoo, he ends up getting forced into a dinner meeting with his family several months after debut and almost forced to give up his career via his half-sibling or other relative (forgot which). Luckily, we have master blackmailer Seohan who remembers a sponsorship scandal related to the relative.
I feel like Siwoo is gonna get the most screen time (in the manhwa) due to him just declaring war on his dad. It’s great n all but couldn’t it have happened in the semi finals or sth. The mc is feeling less n less like…well the mc. I see more fans (in the manhwa) fan girling over all the other characters except him. N the author didn’t even change his hairstyle. It’s the finals come on T^T
