It’s not a plot hole just because you didn’t understand or didn’t see it. I’m not just saying this to…
That's why I asked this question ^^ I think it wasn't THAT clear bc as soon as she erased herself from Sun Jae's life they showed that she was back to the future, leaving all these details implicit... thx for clarifying
I know I'm a bit late but I didn't watch this drama while it was airing... I'm asking anyway: when Sol went back to the past for the 3rd time, how did she become friends with Tae Sung? I think he mentioned that they've been friends for 10 years, but the show never mentioned how, plus in the first time line he never became a cop and dropped out of school... Is it a plot hole?
