I don’t actually know what agreement they will have (since I can’t read Korean), but according to the raws, it doesn’t look like they’re gonna get engaged, I guess pretend to be lovers ? I’m not even sure of this, I don’t know lol, it’s just a guess.. Anyway, she will ask him to help obviously, because technically a part from him, no one is higher than the duke, since there is only him left in the royal family

No, they'll help each other.

Ginger wants to break the engagement, while Izana wants to avoid the nobles who are trying to marry off their daughter to be the empress. Ginger never hides her interest tho, since Izana can read her mind. But he's all like yea you're adorable, i like you but not like that. It's really cute bc Ginger is blunt af. It's not translated yet but I read somewhere that Hamel Bray will develop interest in Ginger, and Izana found out (i assume he read Hamel's mind) and that's how Izana started to get uneasy.
I'd bet 50 bucks she goes to the prince and asks his hand for marriage. too bad I read the same plot over and over... FL asks help from ML or some other man to save herself from despair (in this case it's marriage). I'll just give this story a bit more time to build up as the benefit of doubt
