I think maybe its a alternate story? I mean the names are same but the hair is diff. In the first one, he never saw her for fifteen years till he became a working adult. In the second story, he seem to have taken her home while he was still a teenager.
I read the second part before I read this one and I got so concerned I was like uhhh who tf is this cAUSE HE LOOKS DIFFERENT IN PART 2??
Also I was honestly weirded out at her reactions of a kid aaaa
