The illusion of freedom of choice quickly dissolves when certain choices are rejected, (trying to sneak past the old man is a no-go, meaning only 1 viable option is ever available) or your refusal to accept propositions will not allow you to progress through the story.
I would not have minded helping out Sun with his pictures, but I find his immediate abusive response to be off-putting. As for the cursed git; I don't think the protagonist is that gullible. And then I'm stuck; no other options left.
If the only way to progress, is to let others take advantage of you, I do not consider this a VN; it should just have been a slideshow instead -no need for choices of player input. Simply watch the predestined path unfold.
Nice graphics, good music and easy UI; but ultimately, in this particular form, not my cup of tea.
