No proof of this. Siwoon saw "Taemin" close his eyes and give up on life. He assumed he was dead. Unless he checked up on him at a later date, there's no actual evidence that Taemin's body and Siwon's soul are no longer around.

i mean i too prefer taemin in his own body, i just cant see him actually going back into it. he should've died, but his soul happened to survive. tbh i hope he does come back though, but i feel like the chances of it actually happening are quite low. but no one really knows except the author so we'll just have to wait and see!

Honestly, as we get farther in I'm getting more and more convinced that he WILL come back.

SAME! SIWON IS THE BEST! T^T

Base on most body swap tropes, I don't think the original Siwon will come back. Although the author can go the unique way. Usually the bullied ones die then the main character lives on in the bullied's body.
IM NOT GONNA READ IT UNLESS THE REAL SIWON COMES BACK! if he come back, tell me. or else i will never continue it, my heart can't contain that much sadness. I CAN'T ACCEPT HIS DEATH. HE MUST COME BACK.
