sorry heart lyrics

I'm sorry 그 말뿐이란 걸 (내겐 그 말뿐이란 걸) Tell me why I let you down Any chance I get I'm breaking down 잘못인 걸 다 아는데 왜 힘든 걸까 To tell you that I'm sorry, heart Nanana woo hmm Nanana woo hmm Sorry if I'm too much Sorry if it's too fast Sorry I'm not holding back Tell me why I let you down . souvenir lyrics spy x family
