Sebastian

I understand that the main message of the film, of course, is that he reached the bottom and managed to overcome his shame and get rid of it. Well, shame may be defeated, but something must be done about pride. He somehow goes through the plot as if he is above everything - above the boring work that he allows himself to do carelessly and skip, above the girlfriend, whom he essentially insults when, after his dismissal, he begins to insult the entire publication and all those working in it, as well as even above the profession of a prostitute on behalf of whom it's like he's writing a book - it's worth almost being out of the mood and he allows himself not to hide his condemnation of the client and imagines himself as something like a boyfriend, not a prostitute. Well, that is, the client certainly got a terrible asshole, but before it did not stop him from stepping over himself and having sex even in the absence of desire, it is as if included in the job description ...
In general, the hero is certainly lucky, and in terms of the fact that during prostitution he came across, even if not the cutest, but adequate, orgies, on which take away the mobile phone, passed without problems, and even at the right moment, this old professor did not kick him out, but supported him. It's too far-fetched.
And the motivation of the character is really unclear and why he went into it anyway, why this particular topic so hooked him that he decided to experiment on himself and write the first book about it. And why did he continue, I think they finally paid him the advance. Like this is supposed to show that he has become uncomfortable doing this? Okay, but this raises even more questions...
