The only reason you do not like Quin is because you can not top him.
Man, if the argument in question is whether the pretty boy bunny cultist or the femboy tsundere puppy witch is the better character, I'm all in on the pupper.
I lean more towards subbing, but hands down, if I'm getting dicked, it's going to be by the cuddly pouting pupper, not the pretty boy bunny. Berwyn's objectively the more interesting and charming character between the two. I think the only reason anyone would choose Quint over Berwyn would be an attraction to pretty boys, and that's totally valid, I don't want to dismiss that- but like.. He doesn't have as much content, interactivity, or scenes meant to charm players. A lot of his conversations with you are pretty dry reads. I can only assume that his 'seductive nature' relies heavily on his face.
I didn't have a boy band phase growing up, so I just don't feel any attraction to him. He feels flavorless.
Honestly, this whole comparison between him and Berwyn is so weird to me, it doesn't even feel like a contest, they're aiming for entirely different demographics, it's just that one is a larger demographic than the other is all. I could easily substitute Cait's entire presence in the story with Berwyn from the start and have a more fun experience with the game as a result- but Quint may as well be a dead fish for all the emotion he evokes in me. I'm assuming I'm just not the intended audience for Quint, just as I'm not the intended audience for hardcore yaoi VNs or any anime all about guys in tight swimsuits.
Cute is justice as far as I'm concerned.
