He tapped on it very quietly.

It was so quiet that someone with higher than normal hearing would need to be focusing very hard in order to hear it.

Raon then quickly but carefully started to follow Fredo down the stairs.

�Raon. Of course, your safety is the top priority.�

Raon clearly remembered Cale�s words so he prepared a spell in order to escape at any moment if needed before flying down.
A moment later�

Shhhhhh-

The mirror opened.
A person who had higher than normal hearing and was focusing harder than ever before came through the mirror and into the bedroom.

�Raon gave me the sign properly. There really is nobody in here.�

That person was Choi Han.
Choi Han confirmed that nobody was in the bedroom before quietly looking at the open path and stealthily starting to move.

�Choi Han. You find an opening to search the bedroom. Gather any and all useful information.�

Choi Han followed Cale�s order to search the bedroom without making any noises.
His movements were so stealthy that even the butler outside the door did not realize he was there.

As for Cale, he followed Fredo�s trusted subordinate Solena and got on the carriage.
Cale leaned on the seat of this now-familiar carriage as Solena started to speak.

�To the castle.�

Solena ordered the driver who started to lead the carriage to the white castle.

Clack. Clack.

Cale leaned on the back of the seat and looked out the window.

�When he is wearing the mask and not wearing the mask� He seems very different?�

He was thinking about what Fredo had told him.
Fredo didn�t know this, but Cale saying, �I will keep that in mind,� meant that he would remember it more seriously than anything else.

It meant that he would record it.
