His mother cheated on his father, and Queen Tamarie probably had known about it all along even before he found out the truth a few days ago.
His mother cheated on him when he was at Raycane palace, and there was even a carriage ready for the pink-haired Queen to ride. To make it more suspicious, the place where his mother had an affair with an unknown man also belonged to one of Raycane's royal families.
From Davier, he received information that the castle belonged to Queen Tamarie, and the Queen also designed it many years ago. That was why Elennora couldn't help but think that Queen Tamarie had helped his mother with the secret affair behind his father's back all this time.
That was the reason why he immediately opened his mouth to speak before King Alvon could say anything in response to Queen Tamarie's offer, and now the brown-haired King looked surprised as he turned his head towards him.
