Opaline like topic of My Suha

I'm asking this sincerely...how do people like the secondary couple? The friend was there with Suha all through the entire situation with the toxic ex. He knows how awful he was he saw the physical and emotional damage. How can he be with Dohyeok? Like does Suha find out? That'd be so traumatizing and would feel like a betrayal, no? Or is Suha not a factor in this when both parties of the side story only met because of the damage Dohyeok did to Suha. I just needed to get it off my chest and ask because this couple really doesn't make sense to me or why people like them if they know what Dohyeok was like in the main story.
