@Swift : He does not know, but is not really going to screw it up. Bow hero screwed up by just doing enough to satisfy his ego and moving on. Greed is patient and likely wants them to leave him alone which makes him more likely to stay there long enough to make sure everything is done right, plus he has accomplices/allies who are not brainwashed self important justice nuts, unlike Bow boy, that he actually listens to.
@JutlandAngel Yea, I know. But, I am referring to him not simply "buying", but -to use a business term since he is a businessman- committing to a "hostile takeover".
According to spoilers (heavy spoilers below. Proceed with caution. Feel free to ignore if you're already contented from the spoilers of others
Greed will conquer said country first. Assign FL position as the head (he considers it bothersome + technically has no experience and somehow has to leave for a time), some surviving nobles/greedy individuals then attempts on her life, and Greed saves her.
After that, they'll have food/supply issues and FL is forced/volunteers (forgot which one) to become ambassador and goes back to her old country to ask for help. Greed summons a dragon like familiar as her ride, spooks her former countrymen, she gets impaled, (I assume its because of the World Dew drink) takes a nap and miraculously gets healed, sh*t happens (like her getting scolded by her father, her getting publicly humiliated (just verbal insults if I remember it right), and her finally standing up for herself), Greed supports her and prevents her from killing said sh*tty father (because he wants her to stay as her pure/kindhearted (depends on how Greed sees her) self. Greed conquers her old kingdom too.
Additional spoilers
Greed has the noble/Imperial faction imprisoned. POS attempts to seduce Greed by slandering FL. Greed sees through her sh*t and lies, gets pissed, chokes her (enough for her to pass out if I remember it right), FL also stops him and while she feels slightly terrible for stopping him, she IS still her biological sister. Noble/Imperial faction starts a rebellion. 1st Prince (the stupid Prince) allies with our MC's. Miscellaneous spoilers include at some point Jill gets poisoned via dirty well water abd 2nd Prince prior to Greed's invasion was most likely to succeed the throne since he was a manipulative bastard and his mother has better standing. That's why 1st Prince was so desperate of support of sh*tty father.
Not sure how to feel about Chris. He's nice and all but I can't help but feel that he was sort of guilt tripping Eliana into letting them stay by quitting his job and seeking refuge with Eliana knowing there's a bunch of people following him, making her unable to refuse him..
