The FL (Adrien) died and how now become Blie (black haired), who is assumed to be her husband's mistress-which, by the way, I think is true? Then, there is the crown prince who might harbor some feelings for Adrien. He went to war and come back with the news of Adrien's death, hence why he suddenly rushes out to her grave and cried. I got the feeling that the blonde prince is the ML but I don't know. The story is confusing, probably because of the translation? But yeah, that's the gist of what I think I understood from reading it.
