Chapter 27 Does Nathan's brother had their own story???

As far as i remember it doesnt. But u can look into them in another story "define the relationship" sometimes they appear in that story

Yes they have! But only novel ver is availabe now. Its called egg benedict

Their names are Kyle and Nick. After seeing them in DTR I thought we would've gotten a side story about them so I was curious about them as well. It looks like their novel was the first story written out of the bunch so im not sure why they didnt start there
