괜히 and 괜스레 meaning? Hello^^ I'm listening to a song and there are a few words I don't understand;; It's 괜히 and 괜스레.. They're in those two sentences: - 너의 손을 잡으면 ; 괜스레 긴장해서 ; 땀날 것 같아 괜히 -> When I hold your hand ; I get nervous for nothing ; I will probably sweat for nothing? - 너와 함께 있으면 ; 나 괜히 부끄러 ; 나 괜히 쑥스러 -> When I’m with you ; I’m shy for nothing ; I’m embarassed for nothing? I don't think I'm right.. Also the song is called 부비적 비비적, I don't think there is a meaning but am I wrong? Ah, and, there is this sentence: 모든 게 궁금해 ; 난 니가 궁금해 -> I’m interested in everything ; I’m interested in you? Is it right? It sound kind of weird to me;; Could someone help me with all of this? I'm sorry if it's too long;; Thank you in advance!^
