I think she meant this one:

Hmmm....but I think the story more matches with vengeance of the doctress , holy chef crazy empress already married and have son but this start with unwillingness marriage
I see. Thought the similarities that they were pointing out was an isekai trope (spy to empress kind). +purple hair lol
Kinda true
this manga reminds me of another similar manga.forgot the name but this feels copied. other one had better drawings and translation even.
