When Jegal Sohi got closer, Chun Yeowun was able to see her hypnotized eyes. Her eyes had no focus and was not looking at him directly even when she was flirting with him. So, Yeowun asked Nano, 'Nano, is she doing this because she's drunk?'
[Analyzing facial muscles of the entity.]
Yeowun's eyes began to shake and white light particles began to scan Jegal Sohi's face. Nano's voice then returned.
[Her eye movement shows irregularities. The entity is presumed to be in a hypnotized state.]
[Sending related information to your brain.]
Yeowun felt his brain stinging while he received information about hypnosis. Hypnosis was an act to impact the target's brain artificially, so that person could be manipulated against their own will.
'She's being controlled.'
Based off the information that Nano sent, hypnosis was the effect of a repeated act that stimulated human senses. Then there should be something that signaled for her to be controlled.
