i get how hyejin is, sometimes when I'm so angry I really can't think of anything else to say. although it may seem a bit irritating to see hyejin not standing up for herself and talking back to the sunbae, honestly if I were her i'd be speechless too, with my mind going completely blank. however, at the very least i'd record that convo and post it on social media, i wish hyejin would've done that instead.
