I have a feeling he’s the one who killed daniel and did all that to their empire/estate ...

I was thinking the same....

Hopefully we’re wrong but i kinda doubt that after seeing the last scene

That last scene is what got me here. I think that he thought his plan worked by him coming to him but when the prince decided to leave anyways, Lion got desperate. Also the path to his kingdom was the only one that wasn't ambushed. I think he figured out that the real prince had a shadow and he had to do that to get the fake one to come to him. I do hope I'm wrong and maybe that's with the author wants us to think up to this point.

But let’s agree this would be such a wonderful and crazy plot twist, I would love that
Of course if is like this I wouldn’t want them to end together hahaha

hehehe...
