It is kinda nonsense
But what from I understand, the imperial family found out that the only person who can smell the prince pheromone is Lee Baekwoo, hence they are trying to take Baekwoo to the palace since he was a kid. To prevent this, his mother had to make a deal, the palace will protect her son and her son will eventually married the prince. Without the deal, Baekwoo probably will never experience a normal life. Plus, the mother never told him that he is an omega because he can’t smell others pheromones except the prince and he never go into heat. So, generally he is safe to live as a beta, which again make him experience a “normal life”
i dont get. like the moms reasoning for hiding, or how is that a sign of affiliation to the imperial family. etc. like did she sold her son? also wheres the dad. also you go beakwon, as a fellow archi student, its plate deadlines over anything else.
