My mate from another time

They claimed that everything in the world had a geographical place, season, period, time, term, age, and epoch. Like the sun in the morning or the moon at night, it may make you happy or sad. Water in a never-ending river, rain falling on all the living things who live and die...
However, I'm not convinced. If that was the case, why did my love die and leave me hanging here in this world? I feel her location, climate, and time are all on my side.
So it means life is so unfair!
I'm just going to be with her for a short time. Then she snatches it from my grasp in the blink of an eye. If there was a way to turn back time...
I'll gladly do so, regardless of if I have to give up all I own. Just to see her again.
Erox Lander and General Andrews
In the age of King Artemis and Queen Anathela, I'm a general in the Kingdom of Wolves. But, even though I'm a prince to my father, who is the king of the other country, my mother is simply a mistress, therefore I couldn't be crowned prince of my father's kingdom since he had Aceller, my half brother and legitimate successor. But still, I'm delighted because I fulfilled my dream as a general, not for my father's kingdom but for my mother's.
I'm not sure what occurred, but as I followed the princess into the portal, everything changed. I'm still an Erox Lander, Andrews But it appears like everyone thinks I'm a jerk.
Andrews, Erox Lander, from their world. And where they know that person is a mystery to me.
What about my princess? Why is she acting so different from the princess I used to know?
