There's no actual "real" Huimin, both Humin's are the same soul same body AND same world, just different timelines, as Iheon most definitely time travelled, just a theory where Iheon and Huimin keeps reliving their past but Iheon starts to remember things and have regretted and tried to change everything.
They both know their "past" but Huimin doesn't see it as his past but from a story, and Iheon had already regained his memories and is trying to change things.
