How do I Change the language from English to a different language?

So i have Need for speed rivals on PS4 and PS3 but the one I'm concerned about is the Ps4 version. see when i went on holiday in the UK I bought the NFS Rivals game for PS4 and went back to my home country. thing is i want to change the in-game language into Korean. I'm not Korean though however, I would rather have it in Korean as I'm not a fan of UK version of English so i prefer Korean (No offense English people 🙂 ). Is there actually a way of changing it? and yes i have tried changing the console language. in this case, it doesn't work, unfortunately. I have tried to see ways of doing it in the game, as far as I know, I couldn't find a way to change it. Can someone help me? Much appreciated 🙂
