For me, this is an illusory choice. I don't remember if Ch1 Anna could avoid being a model? If so, my choice was ignored. I don't like anything like that in games. So why is there a choice in which Anna had no experience? Since the game treats her anyway, she has experience. Weird and illogical to me because dev should make a separate scene from being that I have no experience in modeling.
Well I can assure you that it's not possible for Anna, not to visit Dilan and start modelling for him. You can choose not to go past a certain point. But then on the second occasion, you have to model once again, but you can limit how far she goes again. The point of all this, is that it's impossible for Anna not to have some modelling experience at the start of Chapter 2. You not liking that content is irrelevant, because that's not where the storyline leads. You might as well say I don't like certain content in a book or a film, and then expect there to be an alternative version where that content isn't included. It's part of the game, and you have no alternative but to accept it, if you want to play.
What you need to realise, is that during Chapter 1 the game was very linear, and there weren't really that many choices that allowed you to take Anna on the kind of path, that you obviously want her to take. As Chapter 2 develops, it will become easier and easier to take Anna along very different paths. So increasingly your choices will really matter. But certain events during Chapter 1 were unavoidable.
For instance Anna had to work as a naughty barmaid, in Patrick's Bar. You could choose how far she went, but ultimately she still had to wear slutty outfits, and carry out certain slutty tasks that Patrick forced her to do, because there was only one route that everyone had to follow. But in Chapter 2 there are completely different routes , so it's much easier to make new content that lets the player avoid more content. But that doesn't mean you can ignore content that has already happened, which you would have to do, to make it so that Anna has no modelling experience
