I'm sure if the story progresses enough we'll see that the girl really likes the guy but this is some cuck-story without being chuck. The childhood friend devolved into his mom for fuck's sake.
If this "Mom" is super serious about being mom and our boi loves this "Mom" as in romantically? Then NTR awaits this mofo. Or this could turn into MILF action ( ͡° ͜ʖ ͡°)
