The characters' actions in the past can create a chain of events that directly impact their future. For example, if a character makes a significant decision in the past that results in a strained relationship with another character, this could affect their interactions and dynamics in the future. Similarly, a character's past actions may lead to a change in perspective or mindset, influencing their decisions and behaviors going forward. Overall, the characters' past actions serve as a foundation for their growth, development, and the outcomes they experience in the future storyline.
