This thread got really off topic, so to answer the OP's question, I had the same problem with Andronikos. Never picked a single flirt option and still somehow ended up in the romance plotline. It made him seem like a guy who can't take no for an answer which was sort of creepy and not at all fun to experience.
Anyway, when I contacted customer support, they said it was a bug. Looks like it hasn't been fixed yet (probably been a year since I reported it). They don't seem to be very good about fixing bugs in this game, at least as relates to the older content :/
