Luna Sophia's Rebirth

I’m Della, an adored and indulged Lycan Princess, who naively believed that true love conquers all.
Driven by romantic ideals, I hid my true identity to marry Alpha Lucas of the Starlight Pack. I thought happiness was within reach, but I never expected that shortly after our marriage, Lucas's fated mate Aria would appear.
From then on, I became the most unwelcome person in the entire pack, and even Lucas didn't stand by my side.
Not only did I have to endure provocations from Aria, but I also had to face harassment from Lucas's mother Elena and his sister Isabelle.
Finally, when Aria announced she was pregnant with Lucas's pup, I couldn't take it anymore and decided to go back to the Lycan's palace.
But why did Lucas start pursuing me relentlessly after I left?
