한시름 놓다 han-si-reum no-ta
To set down one major worry that had been weighing on you
'시름' is an old-fashioned word for a nagging worry, and this phrase is about putting exactly one of them down — not all your problems, just the one that's been sitting on your chest. Passing a big exam lets you '한시름 놓다' before the next one starts.
