On that point, I think this time it's not as free of a slam dunk victory even though we see blonde coming back in here to talk with fucboi again. She does leave him some parting advice but both of them feel like they are admitting that not everything is going as perfectly because Sakura after her chat with Mio 1 month ago has found her "core" for acting which is apparently using her body to show of the "art of sexiness" or whatever we want to call it here, and she can't be controlled as easily because we see that she ended up taking the offer despite fucboi being so openly against it with her.
This conversation rather than hinting at a potential fucboi character development looming in the final chapter, I feel was meant to showcase Sakura's offscreen development where she has found her "core" and is making her own decisions for better or worse. If agency troubles surface for Sakura in the final chapter because her "pure and innocent" image is now warped, maybe she even transfers to Mio's agency atp.
