To be fair, that poll was before Chapter 10's Minerva content, which elevated her significantly as a character. Before that she was just a mean horny bitch for 90% of the time.
Meanwhile Louise only proves how pathetic she is with each passing chapter, losing the few likeable traits she had. "Insecure" is becoming her main (if not only) character trait. It's a shame, really, as hotness-wise she's definitely up there. She's probably the only character that I have a 0 relationship score with despite sleeping with her. I don't sleep with Minerva on my main save, so I have 0 relationship with her as well (hate being a suck-up), but I definitely started to appreciate her character more. Her cynical view could somewhat complement my dreamer Ian's unrealistic expectations.
