Sticks 하다 straight onto a sentence that ends in the formal-polite -ㅂ니다/-습니다, quoting it word for word: 접니다 하면은 "'yeah, it's me,' and then...", 죄송합니다 하셨네요 "she said sorry". The quoted words keep their stiff, polite shape while the sentence around them stays casual, and several of these lines are someone re-enacting an awkwardly formal moment — 오늘부터 잘 부탁드립니다 하는 그 어색한 상황. The full form is 라고 하다; dropping 라고 like this is purely conversational.
