and he definitely is, I'm looking at raws for chapter 2 and he is casually talking with the admiral. I've google translated some parts and it seems like he is also on a mission and he is in the navy same as the admiral. He does seem to honestly care about the MC (maybe even love her) but he is fooling her by pretending to be a pirate while he is in the navy. At least that is what google translation says
CESAR ((((((
My heart is already aching for him. I mean, I wonder if she is sincere at all that she loves him (
He might be a spy, but probably changed his mind while on the mission?
lol everyone's discussing Cesar
he might be a childhood friend bcoz he knows her secret (unless it was an accident) (or if she ended up trusting him a lot)
