Robert is definitely the biggest miscast in this game. Totally unbelievable how a woman like Lena should do something with someone like him.
In my playthrough he was first knocked down by Axel, then kicked by Ian and finally rejected by Lena.
Yeah, I have received in the past like 2 explanations of what Robert's role is supposed to be in the game, one said Robert was meant to be a boytoy for a mean Lena to use and abuse, and the other said Robert was supposed to be a light version of a gross partner for the main girl (in the sense of what Arthur was for Ash in GGGB).
But I really feel like his character lacks appeal for both roles, I don't really care for the kink but I figure people that do think he's just not "gross" enough to work as a fetish (maybe EvaKiss was trying to introduce him as a douchey fucboi and see if that worked for the whole degrading fetish).
Now for the boytoy role, I feel EvaKiss just made him far too unnappealing, I get not wanting him to ever outshine the actual important characters, but she should have only made him either douchey or a bit of a loser, not both. I don't care how much of a nympho you want your Lena to be, she pretty much always had better alternatives than Robert.
Also Lena doesn't seem to ever like, really start abusing Robert so that you could maybe give a femdom spin to his route. Sure she gets to keep her restaurant job, whoop dee doo. For this dynamic to be interesting I think Lena would have to be getting Robert to cover shifts for her and take her to expensive places or buy her things she want, but that hasn't really been the case so far.
