Yaoi Godsss make it hppen that heesooo is actually an omegaaa, that he just had a wrong gender test (/TДT)/
But that's so boring though. Why build this whole story up with our relationship, as readers to the characters, knowing Heesoo as a beta, only to trash that relationship and be like, "nah Heesoo is in fact actually an omega" like that's cheap. Makes no sense. Just for a baby? I'd rather some mariacle and Beta Heesoo had a baby, than him being a surprise omega this late in the game.
