The story moved really quickly. Chad and Connor gets placed together when Chad needs tutoring for Calculus. Upon meeting they know they're alpha and omega, respectively. Chad decided to pursue and seduce Connor. Connor himself wants Chad, he's had a crush on the guy for forever and he wants to lose his virginity pretty darn bad. When Chad invites Connor to his acapella concert, Connor jumps at the chance.
There's really almost no time for them to get to know each other. They sleep together, have their first fight, make up and have sex with the intention of getting pregnant. The knotting happened for hours and was suppose to give them the time to get to know each other and talk out stuff. Reader's don't get to see what they talk about and I think this would have added depth to the story and helped character building.
