No worries. As of chapter 25 (most recent chapter).....SPOILER
Fated pair isn't mentioned. There isn't a fated pair in Love Shuttle's universe thus far. If anything, ch 24 makes it seem like Doyun and Taehan are the fated pair since Taehan is the only alpha that seems to keep Doyun calm
basically fated pairs (in other omegaverses!) are alphas and omegas that are connected by some kind of soul bond, so when they see each other they cant help but be attracted to one another
Fated pair is when an Alpha and Omega become a pair with no choice or automatically, only they can sense each other and know if they are the love of their life kind of thing.
Usually they would show this 'fated pair' scene by meeting each other for the first time and they could sense strong pheromones emitting from each other, that's when they know they will spend the rest of their lives together.
There are stories where Alpha and Omega hate each other but because they are fated and uncontrollably attracted to each other they end up together. Or because they are fated the seme would pursue the Omega.
What exactly is fated pair, why is everyone talking about it ? Sorry i haven't read anything related to that, in that case is taehan and doyun a fated pair
