This song is about someone who misses someone they used to be with and the first phrase I'm sure you've guessed already means "I want to see you again" I'm sure you guys have all heard the phrase 보고 싶어 before which means I miss you but in a literal sense the words mean "I want to see you" so in this sentence with the 다시 -- it means "I want to see you again" 😭

The first phrase literally translates to "Don't be mistaken" but in this case of the lyrics it is a little more savage! It is the same as saying "don't get it twisted" Use this phrase to sound super fluent/native!!! But remember that it is very informal~ 

I selected the second phrase because there is a word in it "굳이" which I think is very rare for Korean beginners to learn but it is very commonly used in everyday language! By itself, if means "go out of your way to" But in context it basically turns the sentence into "if you REALLY _____" so for this one it means "If you really want to, you can test me" 

  

Can you guess what this phrase means?! Honestly from the break down I'm sure a ton of you smarty pants already got it but this phrase basically means "Worry about me, I'm not okay" It is the opposite of what people usually say which would be "걱정하지마" which means don't worry + 나 괜찮아 which means "I'm okay." This lyric is telling someone to worry for them because they are not okay which is really sad 😭 The song is really good though so let me know if you have other phrases you want to learn from it below! ❤️
