This made me re-read Define The Relationship

Of course but it’s not as popular as Nate’s brother in law Karlyle and his partner Ash in define the relationship (it’s here by the same translator) but Nate’s brother (I forgot his name but the middle child I think) is in the novel eggs Benedict! (You can’t probably find it on wattpad) but if you mean the older brother no they don’t have a novel of him

You can find*

Actually Nathan is the oldest brother and yes the novel Eggs Benedict is about him and prequel to Define the Relationship.

Yes I mess up the siblings all the time
