Heh, I can understand your point. As I've shared in another post, "No sudden Chads will appear from nowhere". But, one thing is certain. The characters will evolve naturally as the events progress.
Hypothetically speaking, a shy and timid character won't suddenly become an "alpha chad" in a few days. That's not normal. Also, a shy/timid character might NEVER become an "alpha chad", cause that would be an entirely different person. IMO a shy/timid character could become more confident, more vocal, more open.
If you've played the game already, you'll see some themes come up often (like the femdom theme). There's a reason for that. But that lies to the story, and this will be further unraveled in the next Chapters.
And to make it clear, this game will not become a maledom game. I think that's already clear from the story. What I suggested in that post was that the MC will become more active.
