the pronunciation of yeonjun from google almost broke meπ his name is pronounced yon-june (the βyeonβ is said more like βyoh-nβ and the βjunβ is said like the month βjuneβ but the βooβ sound is softer/less pronounced which is why itβs spelt βjunβ instead of βjoonβ like namjoon).
in the future, if you want to look up pronunciations of idolβs 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 itπ
