>>66882008If you trace it to the beginning, it goes all the way back to her early "emotionless" days when her self-esteem was so bad and she seemed so lost and directionless I unironically worried that she might kill herself someday. The first big shift away from sexually void deadpan character was when she opened up to the possibility of thinking of herself as cute as a way to improve her self-esteem. I actually still remember the exact stream when she first talked about that in late 2020. That's about when she started to purposefully talk in an overly cutesy high-pitched voice, which is very noticeable if you watch streams from early 2021. It took her a while to find her natural voice (and I really mean "find"), but that shift was the first step for her to learn how to be more expressive, even if she had to force it at first (heimin were teasing her about that shift in expressiveness just this last mengen iirc). Anyway, the line between cute and sexy often gets blurry, and a little bit of sexiness' started to creep in, very slowly. It was a gradual increase over the course of years as she became more comfortable with it. I mean, it was definitely intentional, but also very tentative at first. Getting positive reactions from heimins probably reinforced that behavior over time, to the point where she clearly started to love it at some point. The most noticeable increase in overt teasing being after she came back from corona and got her nurse outfit (I don't think it's a coincidence she released chotto azatoi at that time). If I had to pick one single point in time to answer your question, that would be it, but that would obscure the whole process it took to get there.
That's the short version at least. That's why when she moans a bit too hard for me to believe she's not intentionally baiting やらしい stamps, it makes me feel proud that she's come this far as much as it makes me hard. It was a really big struggle for her, learning to fight back against her self-deprecating tendencies and unashamedly project a positive self-image (her first 3D live is literally called "is it okay for me to be the lead?" for fuck's sake), and she's always been very open with heimin about her feelings on those things, so it feels really personal. Also, it's 100% the idol experience.
