Teen sunjae faught the killer and got him arrested. So I guess he came back for revenge and after killing sunjae…
She relived her past life within 2-4 days in present time line. The things are happening so fast in IS's life that she do not have time to think. Its only how I see IS's journey. She was trying to think about her car accident but couldn't remember it until she was in an extreme situation similar to the one happened to her earlier.
Why did the taxi driver kidnap her in the first place, in BOTH timelines? Was he just being a creep preying on…
I think that remains mystery for the second half. Or maybe during their time travel they figure it out what actually it is about. Secondly, the way taxi driver was preparing himself to kill IS shows that he is a psycho/murderer.
