다는데

They say, and about that

It passes on what someone said and leaves the sentence open for a reaction rather than finishing the thought: she said she saw you there, apparently there is one more secret, they recommend pairing it with the sauce. Because it is deliberately unfinished, these lines mostly end in a question mark or trail off. With 겠 in front it reports somebody's stated intention, sometimes indignantly, as in the line insisting he will call his dad.
