My theory is that Min Woojin saw "Taemin" close his eyes and give up, and wrote him off as dead. If you look at the scene when he closed his eyes, there were no doctors rushing to try and resuscitate him. He was only 18 and perfectly healthy before the accident, so I doubt they would just stand there and watch him die. That means he didn't die at that moment.
Though it is possible that he died after that. But my opinion is that if Taemin's body died, we would see Taemin getting some kind of closure by visiting his grave or something. The fact that we haven't gotten a scene where Taemin confirms his body is dead and Han Siwon's soul is departed tells me that they aren't.
Maybe he's too afraid to see his own grave but I admit there'll a possibility that Han Siwon is still alive because we don't know where is the body.
But we don't know he's dead...? Woo Jin doesn't have to lie in order for that to be true, either. Remember? He looked at Woo Jin as if he was a stranger. That's all Woo Jin would need to believe he's dead, because the Taemin he knows, the only other person he cared for, was no longer in front of him, so he might as well be dead. T.
Yeah somewhere I wish the real Han Siwon is still alive and told all the truth to Woojin
Hey, guys. I'm just gonna post the scripts on Amino and share a link here, because Mangago has given me so much trouble posting them. Sorry for the inconvenience. Let me know if you have trouble reading them. But I will still make sure I share the link every week! I just don't have that extra few hours it took last week to get the posting to work.
Here is the link! Enjoy! http://aminoapps.com/page/what-lies-at-the-end/2724424/spoilers-english-script-for-chapter-49
What a freaking cliffhanger! Dammit!
