This manhwa is using the concept of omegaverse where alphaxbeta relationships is frowned upon. Kinda like how gay relationships is in our real life. The concept of alphaxbeta is considered as disgusting, immoral and no point since alpha is big on passing down genes. His father having liking beta mens have absolute dogshit personality where he would bring yeonoh to watch him fucking beta men. The reason yeonoh refused to touch gihyeon is coz he refused to be like his father. Thats why he hated when gihyeon confessed, coz he only wants to adore gihyeon from the side (wet dreams) but refuse to accept that he likes gihyeon. Coz if he admits that, he thinks he is through and through his father’s son. What he despises the most.
But he told gihyeon that if he wanted to get off he would bring him some omega! How is this love? And he knows indeed that gihyeon like him in a sexual way!! I just don't get it... Like he is a fucking alpha how could he resist his desires like that and rejected his boyfriend? Something wrong with the plot!!!

Guys I'm on ch7, and I got very confused, like why wouldn't the Alpha have sex with the Beta even though they are dating? I really don't get it.. But please don't spoil it
