That's exactly how the game works. You can be good with some and bad with others. When there are multiple characters, you persona with the 'main' character sets the tone for choices.
By main I mean the character who's scene it is. For instance, the pool event in the latest version was Kimberley's event, even though Patricia and Alison are in the event. This is why some options are determined based on your affinity/persona with Kimberley.
Others questions I've seen:
Q. Can you avoid the lesbian parts of the game?"
A. It depends on the love interest. There are solo paths that don't include other women (e.g. Kimberley's bad boy path). Other paths involve groups (or eventual harem).
Q. Why is the Smartphone only available in the freeroam or location choice screens? Why can't we have access to it all the time?
A. The simple answer is when you exit the smartphone, it advances the game. The freeroam and location choice are waiting on a specific response, and therefore, the smartphone has no effect. But in normal dialogue or menu screens, the smartphone would cause the game to advance. In the case of menus, it causes the default option to be selected without player interaction.
I am working on it, and will hopefully introduce something in a later release.
Q. Why am I locked out of certain choices, such as feeling Maria's tits or watching Kimberley change?
A. These specific choices depend on your persona with Maria/Kimberley. In this case, Bad Boy.
The level of points you need to achieve Bad Boy will depend on the difficulty you set, with easy needing fewer points than hard mode.
Q. Why isn't there a 'gallery' mode to unlock or replay scenes?
A. The game remembers your choices, as well as your affinity and persona with each character. All these need to be considered, as a scene may reference any number of variables. It's on the 'to-do' list.
Q. Can I accept multiple jobs?
A. Jobs are not a separate game mechanic. They're just a way for the player to interact with characters.
You can accept as many jobs as you want. You generally get a choice, such as Keira reminding you to work after class; you can blow her off and go to the park. Or Mr Adams asking you to work, you can say you're busy and go to the pool with Kimberley instead.
