"Secret Rendezvous-2"

"Hmm… well…" Sigmund remembered the days when Ivory still had no full control of her extraordinary mana. 

The first time he knew of her lingering feelings for him was when Ivory practiced doing an Advanced magic technique in Greensteid forest. She converted the water into fog, but she lost control of herself. Sigmund recalled that it was the first time they kissed. It was also in his memory the time when he gave her hickeys on her body, but she suddenly lost control of herself and seduced him. 

Whenever he recalled those times, he'd form a smile on his face. He knew they already broke the ultimate rule, and he mentioned it to her again, "Deep inside, I was very happy, but I couldn't admit it to you. You know the ultimate rule, Servants can't fall in love."

"I know."

"What a similar scene," Sigmund commented, then chuckled. He knew his Master would not remember, and she raised her brow in confusion, "We already had this kind of conversation back then."
