the pronunciation of yeonjun from google almost broke me๐ญ his name is pronounced yon-june (the โyeonโ is said more like โyoh-nโ and the โjunโ is said like the month โjuneโ but the โooโ sound is softer/less pronounced which is why itโs spelt โjunโ instead of โjoonโ like namjoon).
in the future, if you want to look up pronunciations of idolโs names, go on youtube and search for it and there will usually be a video in which a korean person is actually the one saying it๐
