Maybe I remember incorrectly, but he travelled back in time and got "reborn" in another body, right?
Then does his before "body" or "identity" exist? Is his before him, alive? I mean Kim Sun In is alive? Or did he stop existing because he is now Kim Su Hyeun? What is the logic? His original body doesn't exist because his soul is in another body? Or did his body reincarnate with another soul?
