Lily's face became red as a beet as she stammered, "Wh-Why are you suddenly saying things like this?"
Damien did not simply say it on impulse; in fact, he truly realized his feelings for Lily. He realized that Lily had long since become his emotional support and someone who made him feel happy, someone who was like the brightest star in his dark and lonely world when he had no one in this unknown world.
Even before he awakened his memories, she was his only true friend who was there for him. He felt that the day she rescued him from the slave market was one of the biggest turning points in his life. He was glad it was she who rescued him and thankful he got to reunite with her.
He knew that if he didn't say anything, he would lose her forever.
Lily was at a loss for words hearing Damien's confession. However inwardly she felt happy, nervous, and a bit excited hearing his words.
