I actually play the domination route. Its just that I change his name to something else at the start so I never heard about Kane the entire game.
It's interesting how I don't recall anyone having remarked they were confused as to who "Olivia" is in contrast to "Kane". Could be selective memory.
Though if true, food for thought: I wonder why this is (Olivia not getting a unique name). It might be another reflection of how certain people like to self-insert whereas clear third party characters, or those that don't fit with whomever they want to self-insert as, don't get as long of a consideration to name as someone in particular.
Might be an interesting question: When you make decisions for Kane, Seth and Olivia, what do you base their choices on? What's your preferred style of play?
I.e. Do you go with the self-insert choices or do you try to choose based on what feels most in-character? Do you include knowledge outside of that of the character? Do you aim for an out-of-character outcome (e.g. choose sub choices since you want to see sub scenes or try to get amass points with a particular character since you hope for a romantic plot), maybe even use the walkthrough outright?
I play Kane sub good leaning on first version playthroughs, mostly to see the Sub scenes first. Seth on the other hand I've consistently tried to play smart. Olivia used to get the Sub good playthroughs first. But after some episode and her dom character making a lot more sense I play her Dom good first. So full on outcome oriented choices all the way for me until I feel confident I've seen most content and a self-insert play follows.
