Essentially, we're going to reconstruct the order of the visual novel after Scene 1 so we can logically connect Diana's character to what happens to her at the end of the night. Introductions will be done in sequential order as originally planned with an appended Scene 2 which will function as an additional "introductory" or banter scene to flesh out the characters to the player more. Scene 2 marks the first "choice" in the demo.

On replay, there should be an option to unlock additional characters.

The player can choose to continue talking to Yvonne, who is the last kinetic introduction. They can also choose to speak with the others. Each interest will have a Scene 2, but the player is not required to read any of them if they choose to. Each scene should end with Diana leaving or the LI leaving dependent on context. Once the player chooses to speak with Robin, however, that marks the end for Scene 2.(edited)
i.e. If they decide they only want to see the Yvonne scenes, they can continue to choose speaking to Yvonne. When the selection tree appears again, they can just choose the "Talk to Robin" option which will then progress the player to Scene 3. If they want to see all of them, they can continue to cycle through the options until the "talk to Robin" option is the only one left.

Scene 3 is the same as before. Robin talks to Diana and prompts her to choose a LI, which "locks" the LI for the following scene. This has no real effect on the long-term.

In Scene 4, Diana pursues the LI who brushes her off for someone else. Dejected, she decides to cut her losses and go home. Forrest introduction has her lose her shoes and Yvonne places them somewhere in the house without telling her. Diana looks for her shoes so she can go home, only to accidentally find the LI biting an NPC. Diana flees, looking for a phone to call the police only to fall and injure herself. Robin tries to help.

The LIs coerce Robin to let them take her to the "hospital".

The LIs get into a car with the unconscious NPC and Diana. The LI chosen by the player initially joins them later before they head to the doctor, where they decide to bite Diana and erase her memories for damage control. Upon biting her, the LIs realize that something is protecting her but they don't know what.

The demo ends.
Consent gets brought up in November, Week 1, by Diana when she realizes that the vampires can eat human food but are not sustained on it alone. Over the surveillance period, Diana questions whether or not she can trust any of them or feel any real sympathy for them after realizing that they don't see her (or really any humans) for what they are beyond food. But hey, vampires gotta eat. Also, no one dies when they bite them so.
