1. Siwon and the original Siwoon died
2. His body died
3. I don't know, maybe we'll find out in the extras
4. I don't why it ended, it ended and you are you
5. "That kid in the bed" is the original Siwoon, Woojin will "die" first because Woojin will take Siwoon's identity and lose his own identity(even though Taemin shows up later on).
Guys who is dying? What happened to his original body? What happened to the evil brother? Why it already ended what is going on who am I? Who is that kid in the bed what who is dying first
