japanese or korean?

hi! so, i recently decided that i want to learn an actual HARD language and i´m between japanese and korean...

i like anime+manga and japanese music a lot, but at the same time i´m a kpop stan+ love kdramas.

i´m sooooo indecisive so if you have any suggestions or thoughts pls lmk!!

disclaimer just in case: i am NOT a koreaboo or anything like that, i´m just interested in these languages since they are very different from mine, plus i find their culture intriguing too.
