How come I can’t remember

I think it was back when he was still running off during the pregnancy

it was after dojin promised to not touch hyesung i think so he went out and brought an omega home and hyesung saw them come in while waiting for dojin to get home

it happened in chapter 13 hyesung was like don’t touch me anymore and then dojin was like maybe i can like other omegas besides him. but then the omega dojin brought home didn’t make the cut and he said his pheromones were disgusting so then he proceeded to then attack the aroused hyesung (i hope this made sense)
