Hello, is there a scene between a girl and a customer? Or monitors or similar devices
Yes.
There is a specific customer, Thomas, whose story is told during the game, as this is related to the development of the plot, and there are scenes between this customer and some girls.
Despite this, these scenes don't happen with the girls on the game's cover, they are secondary characters.
There's also a scene between the MC and a female customer, Erika.
