Be prepared to apologize. A lot.
Nothing says you’re sorry quite like cry face.
Please note that these terms are not meant to be used to express sympathy for another’s misfortune; only regret for what you have done wrong.
Also, If you want to say, “Excuse me”, see the post, Cramming Korean: Excuse me.
