I just saw the new update. And inevitably I have some points to make
The argument is poor and detestable. There is no gradual change in Sofia's mentality. Both her two children, especially her macabre and envious sister, and this friend Vicky, do not "persuade" her, on the contrary, they pressure her immensely, until they force her to do what they want her to do.
In short, each of them wants to satisfy their obsessions of lust against Sofía, and at the same time, it is an indirect way to ruin her stable life, which is evidently a reason for "envy" in all of them, because otherwise, the Sofía's first refusal, they would stop insisting to the point of pushing her to abandon all the parameters of married life that she, with successes and mistakes, but legitimately built with her husband.
I would much prefer that the elderly manage to strip her and suck her, or the route of formal blackmail, with all the characters who want to get involved in that route... minus the farcical and hypocritical attitude of her closest loved ones, willing to ruin the Sofía's ordered life, in order to force her to become a whore.
They are points of view, naturally. This is mine, after also seeing this update. Aesthetically very beautiful, with a too soft erotic tension, but to which I will not object anything in artistic terms
