Looking at Rayze's face which was filled with joy, Yue felt uncomfortable.
She felt that if Rayze did not exist, perhaps she and Hikaru would have been a perfect pair of swans.
However, Yue also knew that if Rayze hadn't caused some problems, Hikaru wouldn't have appeared either.
Remembering what Rayze did, Yue hated him even more.
"That's right. I... I felt a bit sad and bored so I played the piano to calm my mind. Don't you like it? Yue said while feeling worried.
That's right, she was worried because she was afraid that Rayze would discover Hikaru's existence.
Yue could guess that Hikaru was also a bit afraid of Rayze. If he wasn't afraid of Rayze, he would have killed Rayze a long time ago instead of avoiding him like this.
'Perhaps… evolved people also have weaknesses. Hikaru might not take action because he doesn't know Rayze's superpowers, or how strong Rayze is.'
