The variable related to Emily's letter belonged to the original prologue, which used a different pattern for managing variables. This variable still appears at other points in the game, but I plan to revise it soon to fix inconsistencies.
Reworking the prologue was a challenging and time-consuming process. We were under financial pressure, which forced us to rush certain stages. As a result, we removed a story block and adjusted several variables, including the one for Emily's letter. If you're playing with an old save, you probably won't notice significant differences. However, for those starting from scratch, this change may be more noticeable, as all thoughts related to the letter might be incorrect. (These are mainly memories of Emily and the MC.)
Currently, relationship points are managed in a more integrated way between the two modes and serve to unlock specific thoughts, dialogues, or scenes in both story mode and free-roam mode. They are earned by progressing through each character's narrative (during the game's story, not in events). In free-roam mode, these points will unlock additional scenes or dialogues, depending on the choices made.
For example, in the Christmas scene, the timing of when it occurs (before or after Marta's route) affects the thoughts displayed. If played after establishing a relationship with Marta, reflections related to that bond appear; otherwise, they are not shown. (In VN mode, Marta's event has already happened, but if you made "wrong" choices, you may not have enough points.) Just to clarify again: relationship points are acquired in VN mode. Haha, otherwise, people get confused.
Regarding the scene with Lorena in free-roam, there will be a casual dialogue between Lorena and the protagonist that touches on plot details, things related to the MC's past in the orphanage. While it doesn't directly impact the story, this moment adds depth to the characters.
As for Ruby, I need to review my notes to ensure the information is accurate, but I appreciate the feedback and am committed to clarifying these issues. Regarding Sabrina's scene, it’s simply a choice you made at the start of the mission to fix the air conditioner.
