while reading 200th chapter I got spoiled about all this begin dream. I was honestly super disappointed and thought of dropping the series. But nevertheless the story kept me hooked so I continue. Later when things got clear I was surprised of how the authors have incorporated the dream element in the story. Rather then disappointed I was amused. I hadn't expected that kind of development. I thought it would be a simple long dream and if Dokja wakes up everything will be gone. I didn't think that he can basically live in the world and like his original body is inside the dream. So its unique haha

Even though he discovers the secret at later part of the story.. he kept denying until he saw him infront of his eyes. He had already discovered the fact that he himself is OD when he realized the world was extremely favorable to him. Dokja also knew the writer is most probably HSY after meeting her in 1863rd worldline. Now about why did he go to extent of dying everytime and not discussing his plan with his comrade. Simply because of probability/power system. Dokja will have to use up lot of probability in the explanation of the plan cause the info he will share is suspicious to star stream hence his action and speech will be limited. So until the time has not arrived he can't share certain info, it will either get filtered or will cost huge probability. Also about him taking over the place of OD is also part of his plan. If he didn't do this the world would collapse. Also he most probably knew wht he had to do because of Disconnected Film Theory with OD cause if you'll haven't realized yet but OD is 51% Dokja who lost his memories and his body shrinked. Hence he took the 49 51 decision, and the only way for this plan to be successful was by his soul being splitting in million and reincarnating. This way the worlds would survive along with him. Now problem arised when the 49% stopped working because star stream was destroyed. If this wouldn't have happened then there were chances of 49% regaining the memories by Disconnected Film Theory from the reincarnation of Dokja. Nevertheless even when Dokja plan failed due to 49% break down, Sooyoung's and Joonghyuk's decision of writing story and distributing it in different worldline brought back Dokja.

The one scene that everyone wish was written would just ruin the concept. Because previously alot of things were written about not getting conclusion. Dokja not getting to read or reach the conclusion and since Dokja represent us we are also suppose to feel wht Dokja feel right. Also the soul scattering and reincarnation got perfect role because of the open ending. It would have been weird if they just said that Dokja's soul reincarnate and dream for Dokja to come back and confirming Dokja coming back cause then "everyone have their own ending theme" would get be useless. Since the dream the reincarnates are dreaming might not be same as wht KimCom or Dokja wanted {all this is from story context} Another reason is just author trying to stating that we are Dokja and since all of our conclusions are different, we can decide on our own of wht type of ending we want. Whether we want him back or not. Or him remaining young or regaining his actual body size etc
