How do you say "Relax!" in Korean Like when someone is upset and you want them to just 'chill' or not worry about it. In English we can say : Relax! Chill. ~ Chill out! (more of a black expression) Cool it! Calm down! etc...... I don't need EVERY way to say --- just the most common please. And most simple / what your friend might say to you if you failed an important exam or something.... Hey, relax! Thanks everyone. Please include the exact English meaning.
