I get obsessed with tracking down translations, so this one felt like a little treasure hunt. If you're asking about English lyrics for 'Always Only You', the short truth is: official English lyric releases are uncommon, but translations definitely exist. I usually check the OST's official release page first — sometimes the label uploads an English-translated lyric video on YouTube or includes translations in the digital booklet on music services. If that turns up empty, fan translations on sites like Genius or YouTube description boxes are the next stop.
When I hunted this one, I compared a couple of fan versions to make sense of poetic lines versus literal meanings. That helped me pick a version to sing along to. If you want the most faithful rendering, look for translations that cite literal Korean lines and then offer a singable version — those posts often explain choices. I can dig up the links I found and point you to the clearest translation if you want, or help compare a few so you can pick the tone you like better.
