They don't. Oldest is the son of the empress... the mother of the youngest was a concubine and have already passed...
The red head brother specifically spoke to the dark haired brother and asked why he didn’t hate him as well since him and the youngest had the same mother. This shxt happened twice before this chapter came out and this empress basically claimed the red head as her own in her own head. So that shxt is just confusing. She might even be his aunt at this time.
Honestly the translation gets rlly fckd sometimes... so I still think their mother ain't the same... I think that was a plot by the empress and the oldest found out and feels bad about it...
But honestly tho... it's hard to say because in this comic the genetics don't genetic at all... like... where did the oldest red hair came from? Neither the emperor nor the empress or the kids mother had red hair... mc resembles her father a wee bit... but the twins look nothing like him... and even the princes and the princess look nothink like each other...
This is not bad... but can be confusing...
That kid is such a cutie. I can’t wrap my head around why the middle brother hates him but doesn’t behave as though he hates his older brother when the oldest and youngest share the same mother…
I’m hoping we can get through the palace intrigue soon because I’m most curious about the stories from the demon kingdom. Like who that kid she referred to is? Why Robert left their realm and why he’s doing secretive shxt that our FL’s aid seem aware of?
