According to the source, it was the one with the knight helmet that refuses to talk with the FL, the one with the count when the three of them were alone and away from the banquet at night.
I believe he is the new emperor.
just like the other person said it's the black hair guy, he's also in one of the latest chaps I think
No. The emperor is blonde. The ML is black hair. According to sources who read the novel (SPOILER ALERT)
The ML and FL were once in a relationship but something happened to the FL's family that causes her to have traumatic episodes which led the ML to erase her memory so she could have a better life. So the FL couldn't remember anything about him and anything before that. Which is why the count was asking her if she remembered anything at all, to which she replied none.
Then, what title the ML hold?
Grand Duke?
Maybe. They didn't really specify any title that the ML holds.
Maybe he's the other duke in the east?
Who is the ml
