Yerp, they're straight up fated mates. It's why no matter in what 'life', Aeroc becomes an omega in response to Kloff's pheromones. The darker side to all this is that Kloff would have killed/abused Rapiel -- if he hadn't already started. There's a scene in the manwha where Kloff is 'dreaming' and a pregnant Rapiel is knitting. When Kloff stands up, Rapiel flinches back and is terrified, obviously fearing he's going to get smacked. The thing is, Kloff can't be confusing this with Aeroc because Aeroc repeatedly claims that Kloff hasn't/doesn't hit him when he's pregnant.
