Seungwon is a firstborn son and heir to the family’s business. There was no way his parents would be happy with him being with a male beta. Him marrying that girl would allow him to fulfill his familial duties and still be with Seongyul even it’s shameful to make Seongyul a “mistress”.
I wonder Junseong was willing to have the heirs based on what he and Seungwon were talking about but I doubt it would eliminate the potential problem that that the parents probably won’t accept their firstborn to be an eternal bachelor and that Seungwon and Seongyul will have to hide their relationship to avoid drama.
Nahhh that’s what I don’t get in these long ass tales with kingdom like marry the bitch and produce the heirs if it will keep them off your back, you know where your heart is. Jizz in a cup and have a doctor dump it in her. You are the god damn king of course you have to continue whatever the hells going on but yet they fight and almost die and the there man almost gets killed, for what? Nothing. And at the end of the story it’s like everyone forgets we still need them fucking heirs…buts its happily ever after.. tf

Mind you he could’ve had twins

The fact that he was going to marry someone else just becoz he wasn't an omega disappoint me,like he was gonna make him his mistress if he was a beta damn
