I've mentioned it before in this thread, but I think Lena is just a more interesting character, and I see her domination in the Patreon poll as evidence of this. She struggles with money problems and guy problems that create tension, while Ian's world is fairly safe. His options for risky scenarios are generally that of a young man sowing his oats, while Lena's experiences often have an element of being seduced, manipulated or liberated from sexual norms by the people in her circle. She's constantly fighting for agency, while Ian feels securely in control of his circumstances. Stories are about conflict, this is a story-oriented game, and Lena has a lot more for the player to sink their teeth into.
