I don't think it's actually realistic anyway? Hypnosis generally takes a long time, a comfortable setting and a genuine willingness to be hypnotized. Also, making someone do something that goes against their fundamental moral principles, like murder, will snap them right out of hypnosis. Wooyeon would never have been put under in the first place if we were going about this realistically.

Dont get me wrong the art is good but this shit is RPE, having seggs while someone is under hypnosis is considered rpe if u dont believe me look it up
