Ohhhhhh my goodness. I hope he's watched enough videos to fight this crazy dude or maybe someone else will come save the day.
Also who is the editor's dad? She said she'd tell her dad... Does that mean her dad is a super legit fighter? If he was then it makes sense why she knows a whole lot about MMA.
@Speederzdk
maybe you're right, because the date of creation of the channel is April 8th 2018.
But the most important thing is this: the release date of the first how to fight video in the ehrgkrTkdna channel is 2019.12.17,
and the release date of chapter 1 of the manhwa is 2019.11.16 in the Korean WebToon.
So the video is after the chapter.
Seems like it's made up just like you said.
