아이와 함께 그려보세요~쉽게 그리는 민화 (호작도 -까치와 호랑이)

My voice keeps echoing during recording... I've re-recorded and edited it four times, but it's still the same. Why is this happening? It's fine when I edit with Blo, but it's happening after I extract it. Please understand. I'll find the cause and come back with a more improved version for the next video~♡
