Is there a novel for this one?? I missed these y/n plots and I can't wait to know what hap...

I'm kinda hoping the twin isn't evil.
Maybe he saw his brothers boyfriend was a piece of shit and decided to get him away from him so seduced him, And because their parents are also shit decided to have him marry into the rich family instead of him.
But that's probably just wishful thinking. They always have the sibling be evil in this kind of story.
I bet it will be something like, the evil twin swapped their results or there was a mistake and somehow the mc is actually a dominant Omega or hyper dominant Omega or something.

Ohh that's a nice twist too, my guess would be the mc is recessive but with a unique ability or it's s fated mate kinda plot. And hopefully the twin really isn't evil coz their face cards are too cute to hate ( ；∀；)
