He might if he slips or something like any other actor, but i dont think it will be because of the "system". My understanding is that the system makes him live through the character roles as if it were in VR and he has no control.
BUT mc only uses it to study the roles and copies what he sees on stage. In other words, hes not actively using the system while hes acting. Also it seems like he doesnt have to physically act out the scenes in the system like ion his first use as knife victim
@Electromaster /HIve Scans "
you're a police" is grammatically incorrect. Police is the organization, police officer or policeman/woman is the individual. However since this is an informal setting, it should just be
"you're a cop" and the same goes for all the other instances
P.S thank you for the translation
