Although I support pregnant and omega eden with all my might (lmao) but actually Hajun is more like omega (I mean like a mother) cuz he nurtures his member. He cook, he took care of the members, he sings, he pouts more than expected, and his best sport is archery. While Eden here is super manly alpha who aced the military training program for idol, and the ace of soccer team. He is like the father of the team lol. He fools around with the young ones, he got scolded, he got pouted at, but still insensitive lmao, even everyone waits for him to raise the chopsticks before eating at dining table.
Oh but Eden is definitely more dedicated and blind for Hajun than Hajun to Eden lol.

If I am a daydreamer, I would 100% hardcore Eden n hajoon shipper who's writing their fanfic and make omegaverse genre which hajoon would be pregnant
