I don't think that Yoseob is the killer (or the only) it's too easy, look Yoseob had clearly psychological problems that the story shows us voluntarily and makes him ideal culprit, I think it's more complicated. It's just a theory but I want believe in innocence of Yoseob, it's finally just a teenager traumatized by his childhood and that deeply loves his brother yes his attitudes is extreme but he is psychologically hurted and I understand this feeling to be feared to lose someone that we really like. Seeing his psychological, we can understand (no justified) his comportment....
And remember of the title "Uncomfortable Truth" why "uncomfortable" ?

Author post recently a page which shows Wolgang with Shin, it's new I think because Wolgang wears his king's uniform. So, if someone can translate what they say it would be perhaps usefull to know a potential release date....
1st panel: There is notice.
2nd panel, Shin: To receive a coronation invitation for any number of people, regardless of age... Wolfgang: I'm sorry..! Eh, Don't be too hard. I heard that my popularity is striking the sky! Thank you!
3rd panel: I decided to eliminate the limit on the number of invitations so that a few people can attend the coronation. Everyone should take a precious step and make a point. For me to work.( last line doesn't make sense to me. but I triple checked.)
Those who want to be emperors for revenge,
Who dreams of the fall of the emperor,
The two of them are the same...!

I tried. Hope it helps.
