I totally agree with you.
The reason he’s not handling the transition well is because on top of learning he was an omega for the first time, he found out he’s being forced to marry against his will, will be used as a slave to fulfill the duties of the crown princess, is expected to give up all of his dreams, accept 24/7 surveillance, and will most likely be forced to start popping out babies the second he gets married. And to be honest, I would be beyond enraged if I found out my parents agreed to an arranged marriage which would strip away all of my autonomy and freedom. And the only reason he was selected is because the royal family wants powerful alpha babies and he has rare traits, so he’s essentially being used as breeding stock. If I was in that position, I wouldn’t trust a thing that came out of the prince’s mouth because in the end, he’s the one who is benefitting the most all while trampling over my life for his own convenience, no matter how much he insists he has no choice. Instead of trying to help his love maintain a normal, happy life while he adjusts to the changes, he happily used school attendance as leverage to force him to start training for the position being thrown at him. It’s possession, not affection when the needs, desires, and well being of your partner always come second to the most minor of your preferences.
It’s crazy to me how everyone’s blaming the alpha but his mom straight up didn’t tell him he was engaged for a whole 10 years! And if you’re like “well it’s the princes fault he’s an omega” that’s not quite fair they were kids. To me this story is pretty on pace baekwon annoys me cause he doesn’t wanna listen or even see a point be made just to be hardheaded, like I get it if I was younger me I’d be like some of these commenters sayin “I’d run away or kms” but now it’s like there were valid points made on safety and he didn’t care once for his own so far he’s just made me face palm and say grown up
