What  basically happened, in the future(around chapter 270 in the novel), Kim Dokja makes a deal with Secretive Plotter : The constellation saves his friends in exchange for anything that the Secretive Plotter wants. Secretive Plotter sends our reader to Yoo Joonghyuk his 1863rd round, where sh** happens. Han Sooyoung made an avatar with a lot of her memories at the beginning of the scenario, and that avatar became the '1863rd' Han Sooyoung. She wants to seal Yoo Joonghyuk, so he won't regress anymore. Like an eternal sleep. Ofcourse, our regressor wanted to die, but at the last chapters of that 'arc', he creates an avatar of himself(2 Yoo Joonghyuks, one with a black coat and the other with a white one) :

'I... I want to die.' he mutters, redirecting his gaze towards me. 'I-.... I want to live.' (something along the lines of that.)

After that, he kills the avatar with the black coat, regressing. One part becomes an outer g** : The Secretive Plotter. The other regresses, and meets 'Kim Dokja'. So yes, our 3rd round is ACTUALLY the 1864th round and Secretive Plotter is the 1863rd regression Yoo Jooghyuk.

Yoo Joonghyuk is an overpowered character, with an incredibly fragile mental state of mind, due to all the trauma and death he witnessed. He distances himself from people and acts cold in fear of hurting himself, with the pain of losing someone. Ofcourse, we have 999, who was the most gentle round. It was the only round where he sacrificed his everything for his companions. Yoo Joonghyuk his character is basically : Distancing himself and building a wall around his heart to protect his sanity and feelings, which sometimes results to him coming over heartless, cruel and as a monster while he isn't.
