Well this story has no logic. But if I have to make sense of the plot I would say - the alpha and beta were childhood friends. They confused their bond as love got into a monotonous relationship. They loved eachother but had no passion. Maybe because of their compatibility. Like the alpha has intense ruts and pheromones but the beta can't reciprocate. Since it's the alpha's first and only relationship, he has nothing to compare it to so all was good.
Then he met the omega and they have actual chemistry. Also biologically they are more compatible- heats and ruts etc. He feels passion and possessiveness now. So this is actually "love" to him.
(Again, I am trying to make sense of a dumb story because like you I usually can't drop a manga once I start.)

That’s the thing that doesn’t make sense though the MC is an alpha he has an alpha parent. He could have had that discussion and figured this out a while ago instead of getting the beta involved to figure out his “biology and chemistry part” I’ve had this discussion with people before and they said the Alpha has been around omegas before and didn’t find the appeal but all of a sudden this guy practically twice his age and In heat = LOVE <_<. If you gonna have the MC be a cheating douche … cheating on your boyfriend with their “mother” I don’t think ever ends well. This is like an episode of Jerry Springer. “Thinking emoji” maybe that’s where the author came up with this plot after watching an episode of Jerry Springer
Also dows anyone know what happened to the betas really HOT and Charismatic friend because I’m still finding it hard to believe that the charismatic friend would not be a good person to talk to. Also I still
Don’t get you physically beat your significant other don’t talk for a while and somehow that isn’t an automatic break up baffles my mind. Even the psychos who mentally screw with their partners mind, like they Try to go back very shortly after…. The author wrote this as if it’s been a few weeks and the betas randomly is like “ WE ARE NOT BROKEN UP”
I don’t want to sound ignorant but is that situation something that is unique to Asian cultures just like the notion of “Sad Love” (sad love is a real psychological thing btw). Do people from Asian cultures really say but I didn’t agree to us breaking up so we are still together?
Literally all the alpha and omega do is fuck. Aside from being possessive of the omega Why is he “So in love with the omega” I just really don’t Effing understand! someone help me please because they aren’t fated pairs WHY IS THIS LOVE?!?!? Was the novel written by a hormonal charged teenager whose brain hasn’t completely developed to understand love 0.0?!?!
