Omg am so sorry for the late reply, i came home tired yesterday and slept like a zombie ♀️but anyway to answer ur question, yes harry had actually made multiple remarks like that in the story that indicates that he know the truth about charlotte, she had multiple suspensions about whether harry know or not, when the author was asked about it she explained that the truth of whether he know or not and why charlotte hasn't asked about it yet 'll be explained through further chapters, i personally think that harry know and charlotte know that he know but neither oe of them want to acknowledge the truth because they are afraid of losing each other, as he is a criminal and she is a cop who is sent to catch him, their love is forbidden, once the truth is out, all goes down.
Hope that helps
