Total spoilers ahead/my theories: it seems that Ley came back and ended up with King Lucien. She also became Queen of Kabul because of the agreement between the Arans and Sir Wolf, and Michael follows her around for ever. Ian turns out to be Lucien's little brother, and ends up with Lady Linua. Sean marries Sharis. The Leon tribe return home, but the Shine seems to have fallen for Ley and visits lots. Everybody has to work hard to fix things, but they all live happily ever after.
Niceee!(づ￣ ³￣)づ
What about Cid? You forgot him xd
It was wonderful even though it was confusing at moments and it did clarify many things like who is legs real father or what the dream let and the King shared or does ley and the king marry or y shine hates Gideon or ...... So maybe you can make a sequal where it explains this to everyone who enjoyed this manga
