So far I understood it like that: he lived his life, then reverted time. So the reality (somehow) got changed to fit two of them. That's why he (adult) doesn't remember nor had any siblings but him (child) remember having a brother. What's interesting is how all his lies (about working there, about having brother) turned out to be true and confirmed by the flashback
this is so different from most manhwas with this trope like I’m genuinely curious how the time travel thing worked- like how does MC’s original body still exist in the 2nd timeline and what’ll happen once they meet? I saw a spoiler in the comments that MC really did originally have a big bro- so now I’m wondering… what if MC didn’t time travel? What if he possessed his big bro’s body? But then it kinda doesn’t make sense that MC retained his skills & everything from past life cause then wth happened to the big bro? I need answerssssss
