I want to ask, are there two versions of the story? I found 1st episode has two videos with different plots. what happened?

guys want to ask about the opening scene of episode 4 on the bridge, in episode 4 it tells the POV of Sunjae who recognizes Imseol, is it because of the effect of Imseol's time travel or is it just sunjae's pov of the bridge meeting in episode 1 that Sunjae followed Im Seol to her apartment. I mean that scene is just a re-enactment from Sunjae's POV, right? It's not the director who wants to show the changes after Imseol's time travel. Do you understand what I mean? hahahahaha
