Although Diana had made up her mind, it wasn't easy to get Boloz to notice her in a short time, and actively approaching her would only make Boloz more vigilant, so everything had to be done gradually.
Gaining the trust of a stranger was never easy, especially when trying to infiltrate the underground school behind Boloz. Diana needed to gradually perform in front of Boloz, leaving her with various hints to make her believe that Diana was an easier target than Lucina.
During this time, Chen Ke tried to minimize his returns to the cabin to give space for Diana's performance, and Diana deliberately spent more time with Lucina, so that Boloz could see her every time she came.
Chen Ke also emphasized the matter of the small hourglass several times and reminded Diana of its danger; even though Diana was a Witch, that did not mean she was immune to mind control techniques.
