No, you're missing the point. Anyone who can kill any other person, they would fear that person. No one would trust to be around Drew. Also, Sterling wouldn't let Drew pick a girl like a reward or trophy. Even for a bad end, it doesn't make sense. I think we are talking about main story. I'm saying only Drew can probably kill Hunter in the main story, because Drew would then be punished thereafter.
I think you think there is some way that Drew can fuck a girl with Sterling in the vanilla story, but that's not going to happen. If Sterling ever tag teams one of the girls, it's going to be a bad end. Dev wouldn't put NTR content in the main story this far along.
