it's the ironic & controversial rhapsody of an ambiguous bert

Is anyone familiar with the song "The First Time Ever I Saw Your Face", first sang and popularized by Roberta Flack, recently covered by one of my favourite artistes Leona Lewis. Someone in cyberspace out there used this song to create a music video of this Korean movie that I liked very much and although I've always found the movie touching, watching it again tonight made me feel more. There is this scene in the movie in which the male lead said:

"is it because I'm not rich enough?? I'll work hard
is it because I'm not smart enough?? I'll study hard
is it because I'm dirty?? I'll stay faithful to you only"
