Maybe it was cause they were like in their teens when they died? I remember them having school uniforms on in their little picture thing
Yeah ig but teens are a little more mature than that what I mean is they still act like 5 year olds instead of highschoolers also the fact that they time traveled is never even brought up in the story again so it was just an unnecessary detail
That's true but maybe they've been toddlers for so long they're getting used to it and maybe that fact was just to add drama or trauma or something cause they already know death
I feel like the whole thing about them dying and then travelling to the past is unnecessary because they still act like little kids
