I'm exciteddddd!!!! But wait, if this is indeed ending up subscribing to the multiverse theory, then older Yeon-ho from universe 1 would be different from Yeon-ho from universe 2 which is still in high school. Even though Yeon-ho 1 was able to save Jae-ha 2, Jae-ha 1 would still remain dead in his timeline. At least Yeon-ho 2 would have a chance for happiness. But that's messed up though. Yeon-ho 1 loved Jae-ha no matter in which universe/timeline. That's so sad.
I was wrong. There is so much drama in multiverse theory.
Absolutely love this! Save him!! I feel like hes not going to be able to save him though... :'(
