oh well its literally what they talk about in this last chapter, but in hyesungs perspective he believed his dad treated her mother badly for being an omega, he would practically prostitute and hit his mother
so when she left he also treated him bad but bc hyesung thought he was an alpha at the time his dad didn't do anything but then one day his dad made a comment asking if he was really an alpha so hyesung ran away bc he thought his dad would do the same thing he did to his mom
so this all explains his fear of being an omega and why when he met Dojin (who btw also used him at first for inspiration to write songs) he didnt trust him and wanted to break away from him cause he in his perspective was being used just for being an omega

ohh I get what you mean,, but I was talking more like use as in sexual object bc what hyesungs been taught all his life is that omegas are just meant for breeding and sex to satisfy the alpha as we see when he got a job which turned out to be omega prostitution. In this case when hyesung wanted to marry a rich omega when thought he was an alpha was bc "alphas should mate with an omega" reason why he never had an interest in betas/alphas and even now we know he has an interest in only omegas (obv apart from dojin), and it would've been a plus if they where rich bc at the time he barely had anything.
I don't know if this made sense..but yeah..
I'VE BEEN TALKING ABOUT THIS FOR SO LONG Hyesung had the shittiest upbringing with the worst parents and bad things just kept happening to him ofc he acted like a little bitch cause he was always scared I'VE BEE WAITING FOR AN ARC TO TALK ABOUT HIS ISSUES AND FINALLY FIX THEM not just give him an alpha who loves him and think that fixes everything but and arc when he can actually heal and forgive his past
