I know you haven’t experienced it but is it like drowning? Brutal先輩
sorta since both lead to asphyxiation which is caused by lack of oxygen, but the pain is completely different from both scenarios, since when a person is drowning, their lungs slowly get filled up with water causing the lungs to become tight like a filled up water balloon.
for the people asking why didn't he torture them, they are getting tortured, very slowly they will lose oxygen and they will die a slow painful death
