I have a feeling she simply knows he'll be back soon (perhaps once again on the Emperor's orders), so it's a given they'll meet again. Why would she keep this info to herself though... well, maybe she doesn't want to overwhelm him or something.
And I'm 90% sure he's the ML,
@LupusVir, but so far the most interesting story bits were their palace shenanigans. I really, really, REALLY fear it might devolve into this generic "cold
northern duke southern admiral" romance if he keeps being close, so the longer they stay apart, the better.
I'm an awful person :C
