I don't know Korean, but I have the impression that the text in the balloon of the 12th image frame is mistranslated? It doesn't sound logic to repeat "Attack!" there, while noticing your opponents are actually super strong. In the raw, the letter also misses a small line in the middle, and I think that sign stands for an "Ah!" or something? Don't trust me on that 'though, the only experience I've got with reading and somewhat "interpreting" Korean is through reading other raw manhwas.
Not sure if Hatigarm Scans like or even read this kind of advice here 'though.
Not to mention, I forgot to be grateful. So here: Thank you very much for translating this gem of a manwha, Hatigarm Scans! ?
