*cough*Freddieplayedpiano*cough* Even though I do believe that a good frontman also knows how to play an instrument, I'm sure there are enough frontmen who don't.
I'm a sucker for time travel, so it always begs the question what kind of time travel someone is going for. Is it going to be Ouroboros, where it's an infinite loop? Is it going to be Terminator, where it's a time paradox? Is it going to be Back to the Future, where the future changes due to your actions? Or is it going to be Flash, where there are fixed points in time but the rest is malleable?
Well, Ouroboros is out of the question, because he already changed things. He replaced Yoon Dong Jin as the guitarist, which in turn changed the first encounter between mom and dad, maybe he changed the future when he saved his dad from the car accident. And Choi Se Kyeong was not supposed to return to Korea until years later, and yet she's back after a few days. Which is the biggest change of all that I still don't understand. How the F does his presence change her trajectory so much that she's come back to Korea to end herself? Yes, I know I know she said that everything in her life went as planned until this crazy person suddenly showed up in front of her school and that annoyed her, but that's still too big a leap to change her whole path. But maybe things become clearer for me in the future.
