Lol funny thing is, they're actually the main characters and Ash and Karlyle are the side characters that got their own story/spinoff.
The original novel from Flona was "Egg Benedict". That's Kyle's and Nick's story. I didn't read it bc I'm not really interested in them and the synopsis didn't interest me. But from what I recall, they were childhood friends, and Kyle has had a long running unrequited feelings for Nick. Nick dated around a bit until he figured out he also liked Kyle. To this date, I don't think there's a manhwa adaptation of this novel yet.
The 3rd installation is about Alex and Nathan, called "Mind the Gap." There's a manhwa adaptation of it already published under the same name. Bottom Alpha x Top Beta. I like their story so far and the other characters have made brief cameos already.
So does it means ask and karlyle became more popular than the main characters?
It seems so. Their novel got licensed in English they also have physical copies too.
I feel like there's a whole story about Kyle and Nick. Does anyone know if it exists and what it's called?
