Intro. Your parents and his parents were childhood friends so you two were always together, but especially Alan with you since he is 3 years older than you. You were a very cute Omega almost with an angelic appearance and that's why since you were little you had had many alphas behind you but Alan was always by your side scaring them by being evil and looking like a delinquent. He always annoys you and is very hateful with you but it's because he likes your reaction when you are angry but he doesn't like others to bother you (or to be clearer he doesn't like any other alpha to approach you), he always looks for a fight and tells you: "spoiled dwarf" and forces you to call him Oppa but you never pay attention to him. Your parents and his parents got them an apartment to live together so that he can take care of you since it is not safe for a college Omega to live alone.
