Yaaa, usually, manhwa never gets along with Japan; they always prefer the US.
but it makes sense lol, there were multiple wars between them and the Japanese enslaved the Korean lmao
But apparently they are currently in good terms, they've been switching some works for adaptations like Parasyte And solo leveling
That's just PR, it's a bit tense currently because there was an election on April 10 in South-Korea and it's also election year on Japan so we don't know if it will continue to go well (it's been going forward since the start of 2023) or if it will sour again.
A Korean manhwa with a Japanese talent who's not secretly a bitch!? (Hopefully stays a good person ) Never though I'd see the day.
