If You Want Me
Blonde is the maid's son, they used to live under a mansion because she was the nanny of the young master. After blonde presented as a recessive omega, and he and the young master kissed, they grew apart because the rich went to the US. The rich alpha returns and demands him to be his sexual partner so he can realise his pheromones, because the omega was going to graduate a great university he accepted because they would move in close to the university and he had a long time crush on the alpha.
Special Benefits for Newlyweds
Married by contract, they both needed to enter in a korean prestigious university, the omega because he was already out of school and needed to pass before he got too old (and to make up for his parents loss), the alfa because he didn't want to go study overseas. They submit to a program made for increasing birth rate by supporting newlyweds to go to university
