" After the Chapter ends (ch.60), Seonwoo wakes up from his old apartment in real world but we realize that the person who actually got back is the Seonwoo from The game (I’m calling him Seonwoo2)
-Seonwoo2 when he was 9?8? Yrs old got transmigrated to the game and realize he was stuck there and he is now an orphan and have to live the life that he got now. So now he realize he’s finally back after all these years and is happy to see his real parents being alive and well and is going to try to live the life he missed.
-He then realize our MC Seonwoo will be the one who got transmigrated back to the game. (But since it was Seonwoo2 whose actually the real person in the real world, Our MC Seonwoo did actually go back to his real world which is the game (I’m calling it the game for the lack of better word)
-Seonwoo2 then decided to live his life and applied to a new job where he met out ML in the real world because apparently the devs of the game (the game our MC is playing) uses real people for character design so Seonwoo2 was shock to see Jehee face because he’s like shii there’s jehee in this world too? And he’s like sum CEO shi
- ok back to our MC and ML shii happen to MC he was in a void for a while and since ML used the regression it was natural that our MC got turn back where he first realize that he got transmigrated in the game (cue to ch1) all those confusing shi happen to MC but instead of Chorok banging on his door it was ML holding a bouquet of flowers smiling at him.
-Mc was then so shock seeing Jehee. While Jehee on the other hand was like “You’re from another world aren’t you? Then decided to walk in and said something like I know you’re confused right now so let me help you."
Apparently there are some side stories too...

I am confused can someone explain to me what is going on? I thought the main character returned home but it seems like the other guy (with the same face) returned.... I DONT UNDERSTAND!!!!
