Akyran's Folly

"When Prince Akyran approaches Ecaeris Reyneris with a marriage proposal, she assumes it's a heartwarming match based on their long-lasting friendship since they were kids. However, she discovers to her surprise that Akyran's true affection lies elsewhere – with his hidden half-elf lover. He goes through the motions of marrying Ecaeris to fulfill the stringent demands of the mysterious Dark Court, which necessitates having a bonded bride and an heir."
