duty after school

My sister suggested Duty After School to me and warned me that the ending wouldn’t be a happy one. I thought I’d be prepared, thinking it couldn’t possibly be as sad as some other K-dramas. My plan was to finish Season 2, just the last two episodes, then watch a new movie. But by the end of it, the trauma was so real, I had to put my phone aside and just sleep because I couldn’t bear the pain and sadness. The emotional hit was brutal. Honestly, it left me speechless.

What was your reaction?
