I think the body still remembers the trauma it went through..physically and mentally.. Taemin knew Johoon from watching the video.. it overlapped each other I guess and cuz of the fear the body remembers, Taemin got the flashback of the video he watched and overlapped w/ physical trauma (dunno if that made sense)..but since Taemin's persona is much braver he got over the fear of the body quite fast... and anyways I'm seriously scared of what lies at the end hehehe hopefully not tragic.. I hope that when young (maybe a baby?) for some kind of unknown supernatural powers, siwon and taemin switch bodies and then when the accident happened they just switched back to the bodies they were meant to be in lol xD jihook and taemin (soul) were the original bros so they have the same personality lol. somethin like that xD I'm seriously fantasizing about this a lot lol

Hmmm will that's confusing !! And yes, I agree with you about the body Response and other things I also thought about this ! But this still makes no sense ! Also Johoon was not visible in the video only his voice was in the video ! So Tamin does not know the person who assaulted Hen Siwon How he look like thought !
Hey Hey Hey wait a moment Why Yoon Tamin Remember About This Person? it's supposed to be Han siwon memories it has nothing to do with Yoon Tamin So why did it appear before him? Love, hate, fear, anger are all about the soul and not the body ! So since Han Siwon has died this is supposed to die all his memories with him ! But the fact that his past had come to Tamin head meant that He's probably is not dead ! ? Oh Lord, I'm tired now and there are a lot of questions going on in my mind That's why I hate "Ongoing Manga " It cuts you in the middle and makes you confused and takes a long time to update Σ(っ°Д °;)っ Lord I will kill myself (╥﹏╥)
