Charles Choi - James Lee - SB Daniel Park
Charles Choi can’t get a second body for himself normally but has a certain condition. He can take over other ppl bodies when they reach their peak. Jinyoung was one of the 10 geniuses and Charles Choi is called Elite. Elite has the same attire of a classical Korean royal family lineage in 80s. Elite must have heard about the experiments in China and he wanted to get a SB but he lacks the medical knowledge, he needed somebody to show and it happens to be Jinyoung but Jinyoung later learned about Yamazaki and betrayal, left Charles. Charles only got half knowledge of the PB.
Charles later found James and trained him up as his successor, James looked up to him and loved him but in truth Charles was grooming James to be his perfect body and take over him when he is complete. This is why he told him to surpass Gapryoung and kill him, surpass all the kings. When surpassed them and completed his body (hinted in chapter 496) Charles tried to take over his body but failed. Due to this James learned about 2 bodies and all the other shady things Charles. He became lil bit like Charles due to the failed experiment but kept his consciousness intact. He was disgusted and angry towards him and to control James Charles used blackmail of Gapryoung murder case and 2nd body Daniel.
2nd body Daniel is perfect plan for Charles. After learning from his mistakes he created a body perfect from beginning with a submerged soul but could not take over it for some reasons. So he had to chose somebody and it was Daniel. He wanted to train Daniel just like James and told him to surpass James just like he told James to surpass Gap.
During the trial for Taking over of 2nd body Charles failed and the submerged soul of 2nd body came to learn about Charles and his plans. That is why he said “Charles Choi comes first”
On the other hand James became DG and was aware of Daniel’s 2nd body. In chapter 513 Charles wanted Daniel to stop DG and in that process Daniel will become the perfect he meant to be only to taken over by Charles since OG Daniel is the original body and real human 2nd body is not.
But Charles failed again it seems but no in truth he took over Haneyeol Baek Jinyoung’s student to learn the full secret of 2nd body from Jinyoung himself and create a 2nd body for himself alone. DG knows it and he wanted to stop Charles Choi and get his hand on PB, this is why he is also searching for Jinyoung.
DG told Daniel that truth about 2nd body would be heart breaking and he never will able to escape Charles Choi cuz James Lee himself experienced it. If you like this theory put a 👍🏻 in comments.
