I think it's just a coincidence from Fargo ( or maybe not) but Byul really reminds me of one of Jane Austin's novel heroine 'Emma' and 'Cher' from Clueless (also inspired by Jane Austin's Emma). The characters are basically pampered, spoiled and quite naive, all arguably negative traits but then they're also endearing, kind and mean well and make you want to root for them.
Byul's probably the prettiest alpha ever drawn. I wouldn't be surprise if the author does a switcha-roo and he is really a super omega or some kind of hybrid of both even if the author decides to go that route. HOWEVER seems like the author also has a goal of pairing all the omegaverse genders together so most likely Byul and Jiwoo will stay alphaXalpha too.
Love how the author is showing the affects Siwoo seems to immediately have over Byul. It'll be a long ride but it's going to be so sweet to see Byul slowly realize his feelings for him. In the meantime I imagine we're going to get alot of 'doki-doki' moments lol.
