I still don’t understand like why is he helping ebony?? Like was it all planned or so?

I don't think it is just about Ebony but about the rights of women in their country. Ebony was just a good vessel to start the changes needed in their country. Now of course it looks like he's catching feelings.

Mece's comment + Remember Ebony was freed from prison because the empress of the country who beat kalcass in war asked for it. He has a different mindset because he was oversea for a long time, their duo is almost a miracle
