I've always been good at pronouncing so it was easy to sing it after listening to it a few times, korean dramas helped. One time I was walking home from school and was going all out in Kpop, I didn't know anyone was listening but when there was a slight bit of silence in between songs I heard footsteps behind me. When I turned around there was a group of Korean exchange students. The look on their faces was priceless! Unfortunately I never saw them again just because they went to a different school.
