Until now I think Rob is the most useless antagonist of this VN .. He's not a close friend with either David/Ana..He doesn't have any information about David cheating, don't know Alexia/kendra, never go to gym, nothing to do with anyone's office storyline....He was just kept in the story as a masseur who is obviously pervert for married women and waiting for his chance. I mean story wise he doesn't fit in any plot..feels like his storyline been pushed for no reason. Like if 8 characters standing online to fuck ana, he's like 9th one saying why not me lol.
