This song is about a boy (EXO) who love a girl. But the girl love someone else.
EXO want to warn her that if she date this boy, she will be hurt because (the boy is not a good guy)
The girl suffer with the boy but she is stubborn.
EXO can't do nothing....All they can say is "stop stop stop this love for him" "don't go too far because you will regret it"
It's adorable
