A lot more nuance is going on. Altho he liked Haewon, he didn't really get to date him. He was too busy just just maintaining what they were. They were exclusive FWB at best. It was a very transactional relationship.
One working theory I have is that considering how his previous relationship/s with alphas have been transactional, it affects his perspective on omega-alpha relationships. What part is transactional? What part is emotional? There's more obligations and complications when you're dating an alpha or omega compared to dating a beta. We havent really seen his backstory to know of theres also some underlying trauma

I loveee the side couple so much what are y‘all on?? qwq The Alpha guy seems like a gentleman and is SO fine, I want to see more of them!!
