Dane is a dominant omega.
Dane made the mistake knocking him out with his pheromones, to get him out of a fire. But having a dominant omega father he recongnized the pheromones scent and that it came from a firefighter. That + the words of a fortune teller made him join the firefighters... .
And Dane, I don't see anyone aside of Grayson getting through to him. Dane is a massive relationship red flag, no smart omega would have bagged him.
He is an extremely rare dominant omega, not a normal one like Josh or a turned one like Yeonwoo.
Actually the author spoiled it years ago on her twitter, and I know when KML was uploaded here someone spilled the beans in the comments, about the pairing and Dane being a dominant omega.
Dane actually topped everything that was smaller than him, even male alphas, he was an exclusive top. Why are you so surprised, it's simelar with Josh, that guy was straight before Chase.
Well it's your loss, because their dynamics is pretty entertaining. The crazy guy is actually a suprised, his strange way of getting through life with all his quirks is pretty funny. And Dane will make him suffer.

Damn chase been an asshole but it’s obviously because of hurt and trauma from his family, and pls wtf is his brother actually ending up with that hot dark skinned dude who was super nice to the omega in the first story??!! Pls nooo why!!
