Earth 

He is knight of the kingdom.  He is captain.  He fights in the wars as if he is going to lose his life.  Because he cares not very much about his life anymore.  Because he lost her.  Eva. His Eva. The woman he loves with his whole heart. He lost her to a crowned prince. The same crowned prince that drools over him like a dog looking at a bone.  

Eva

She is crowned princess.  She was the lover of Earth.  And she loves him very much.  But money, comfort and luxury mean more than love to her.  That's why she chose the prince over him. 

Hugo

He is crowned prince.  He loves his kingdom.  He could do anything  for it. Anything but give him up. He married Eva yes. But only for an heir. He loves only "Nicholas".
