I read a spoiler post before, but I can't find it anymore. What I remembered is:
Jaewoo came into the novel because the 3rd guy irl is scarily obsessed with him. The 3rd guy's younger sister was the one who put MC into the novel to help him escape. The 3rd guy kills Jaewoo to take him out of the novel. However, he and his circumstances are so miserable that he begs the sister to put him back in the novel. He transmigrates in with his real body and eventually meets with Hyeonjin again. It takes Hyeonjin a while to recognize him, but they eventually reunite.
Everyone seem to view the 3rd one as an antagonist but he is probably the end game, no ? Because I don't see thing going well if he choose any of the original MCs of the novel. This manwha is really weird because at this point we should have strong hint at who we win over MC but I still have no clue at how this thing will end. :x
