Though, I feel bad because let’s say it’s not intentional for the uke to make the seme fall in love with him when they were just kids, but it was impossible not to love him when he was always at the seme’s rescue. Then he was the one who said he’d marry seme. Now that he presented as an omega and the seme as an alpha, he’ll just forgot all about the things he said to seme before? Like, I feel bad for the both of them. But I still love this tho. XD

Overall, it's incredibly tragic for both. It's bad for the Omega because he doesn't want this relationship; he feels uncomfortable, he is unhappy, he wants to avoid it all. It's like permanent abuse, primarily psychological.
It's bad for the Alpha because he is completely obsessed with the Omega, he is fixated, and he doesn't know how to live any other way, and it makes him feel terrible. And it will never be the way he want it to be
It's impossible to build a happy relationship by breaking the freedom and will of one partner. And that's truly sad.
