For koreans,,,is that true ? 안녕하세요 :) I noticed recentlyin K-Drama that "ㅁ" sometimes is prounouced like "b".. is there any irregular rule ? For exemple : instead of saying "mi-an" (미안 ) I hear the sound "bi-an" (in the meaning of Sorry) or instead of saying "moe?" (뭐 ?) I hear the sound "boe". (in the meaning of what) Would you like to help me understand that ? Thank you in advance :)
