I have read until ch.48 from another language translation,
They won 2nd place, and that KAMA-something show decided to change the content, from 2 singer to 6 singer, that’s why Millionaire get to perform there.
And that antagonist u said is true.
That Henix’s leader was somehow look childishly cute like a hater that don’t realize he’s a fan, but this man is the worst type of person. He was the not-so-original songwriter of the “Crazy” song whom we have been told in the manhwa before that he got into a scandal of SA/SH woman.
And yessssss!!! In less than 10 chapters, he harassed 2 women and proceeded to threaten one of them. The biggest trash eveeerrr (╯°Д °)╯╧╧
Raws of this since the raws are at Chapter 50 now... Though there will be another antagonist there that looks like Orochimaru 'coz how snake like he was drawn. I think by "context clue" they won the Jungle show (not really sure though) since they were at the awards show...after the Jungle survival game show arc
