Did I miss something? How do you know they're from different times and not just different locations? I saw another comment that said something similar so now I'm genuinely wondering if I missed something.
Ah, in the first chapter, you see those poster models on the wall, the models's hairstyle and clothing were like the styles from when our parents were young. In her first dream, there was supposed to be her apartment after the turn, but she found the male lead's place instead. And you can also see overhead cables at the background in first chapter. I think she's living and working at big city like Seoul and most cables are installed underground now. So, all of this is just observation and guessing so far. We could be wrong. ╮(￣▽￣)╭
Umm, I hope my explanation helps although my answer might be confusing.:-D
Nah, you're explanation was good and easy to understand so I appreciate that. I feel dumb for not noticing all those details(guess I was just distracted by 'em steamy scenes). Good catch and I hope your theory is right (๑•ㅂ•)و✧
I'm curious how this story will end since they were from different time lines.
