I think it's more so that he forced him to wear a collar that only he can take off. It's the lack of consent not the collar itself
really? I read other abo manga and just be thinking about gifting a collar to the omega, the alpha knows the omega would be angry
Oh, maybe it's just the ones I've read then. Usually in the ones I've read the collar is seen more as protection/an engagement "ring" so I can see why a partner giving you one without talking to you first would be offensive. In some other ones it's seen more as like something to bind you to them. I still think it mostly comes down to a consent though
why is it considered disrespectful for an alpha to give an omega a collar? isn't better then being bitten by their alpha, like biting too soon or without the omega consent, or by random alpha?
