hmm i don t thik he reay hated him, more like felt a strong jealousy and inferiority complex to the point of almost like hating him (if that makes any sense), also i don t also think he s an omega, and yeah he wanted to become a prefumer cuz the person with that particular scent saved him, and to achieve his dream he cut his throat to provably earn sympathy and so he can leave the family business and become a perfumer .... so he had Jae moon as his stepping stone, making him suffer a bit by blaming him for stabbing him as a revenge?
But since he never truly hated him seeing him uncouscious on a bed for tge 2nd time(remember the memory loss) but this time for getting hurt for the x time and seeing the cute omega suffer silently probaby made him feel weird and bad for what he did before..
These are just speculations. Sorry for any typos i m only moving my fingers , not even my hands lol
Well i believed his gender was never told and the rape attempt on an alpha is really out of place on omegaverse, unless there is a special situation.
Also i like your theory about cutting himself for sympathy. But if thats the case, the authors HAVE TO say it. Otherwise the author probably didnt know how to give a propoer explanation and just gave an half baked backstory.
And i guess its really just jealousy. But blamimg Jae Moon for the cut. And years later, he tries to steal his lover. And now, he finds him unconscious and suddenly regret?? We deserve a character development for such a big change, otherwise it feels very odd.
yup it does feel a bit odd and i tried imagining what the author could have thought about and comparing to situations i know... so i imagined him as a character who would harm jae moon but doesn t want anyone else to do so, and that was the reason why he felt sorry.... and for his gender yes it wasn t mentioned so idk.. and rape attempts against an alpha aren t that uncommon, at least in some other omegaverses
There are rapes on alphas. But its much more rare
Like Omega rapes is everywhere. Alpha rape is kind of rare, but still there.
But my point was : if theres an alpha rape, its a special situation, aka we have more explanation
Like for omega rapes,we dont need any information. They are so common that they dont even need to explain to us because omegas always get raped
But alpha rapes are more rare and not a normal thing in the omegaverse. Therefore when they happens, we usually are given a proper understanding of the situation. Such as 'he was kidnapped' or 'he owed money' or "the alpha boss sexually harrassed him.and he cant refuse or he might lose his job".
But here we get the classic : random man tries.to rape without any information. Which is more appropriate for an omega.

Okokokok i need explanations about this backstory!
1. So is that dude an omega????
2. So he became a perfumer to re-make the scent that he loved so much, right? Then why did he cut his throat ?????
3. Even after blaming Jae Moon for the throat cutting, why does he still hate him so much ?????
4. Lol and why is it only now that he regrets???? Im confused. Hate him all the way or dont. Dont just switch randomly....
