And Define the relationship manhwa's:
https://www.mangago.me/read-manga/define_the_relationship/
Completed btw
Are one of these characters in this manhwa related to karlyle ? Is one of them his brother?
I think they said Blondie brother turn into an omega and I think that brother is karlyle brother' s partner
Nick
Kyle is Karlyle's younger brother. He's an alpha and Nick's partner. Egg Benedict is about them and it happens before Define the relationship.
And Mind the Gap is about Nathan, Nick youngest brother. And it happens years after Define the relationship technically
Does egg Benedict have a manhwa
No :(
The novels are not related but they happen in the same universe and the characters are related.
The order would be:
1. Egg Benedict (Nick & Kyle)

2. Define The Relationship (Ash & Karlyle)
https://www.novelupdates.com/series/define-the-relationship/
3. Mind The Gap (Nathan & Alex)
https://www.novelupdates.com/series/mind-the-gap/
You don't have to read all the novels to understand the others but, I think it's better. Espe because Nick and Kyle appear in DTR and then you know their story. And Nathan also appears in Egg Benedict.
