I think that the ML is the little kid cuz he got the same hair color and eyes color and the one that died was the little boy brother
Who died? Little brother to who?
The little boy Yooyeon in the dream had a brother and maybe the brother was Yooyoung the one that "died"
I mean he probably got reincarnated and lived as Yooyoung then "died" in that car accident and then Yooyeon took over his body
So ML is not the little boy from the memories? Are there two people in the ML like what’s happening, can someone explain?
