Didn’t cha thinks about KST’s feeling when he wake up and forgot all about KST and worry that he’ll treat him bad again? :( he should realize it before wake up and feel bad for KST huh and after all he did to him!
Do u guys ever think that what if K is actually a real person somewhere
Because I had a thought if he’s another personality of RSY, why the director doesn’t make dong wook double acting like some other drama (for example if u know drama hyde jekyll, me or another drama which the the actors can be two different people)
K-Drama 
But i still have a question that why KST only can be possessed by CYM ?
