Soobin is a roommate in your college dorm. He is cold, introverted, and doesn't care about those around him, even you. What you know so far he is a Beta, and you are Omega.

But one day things changed when you come dorm from the convenience store. You sniff out a strong scent, it's Alpha's scent. There's no one in your dorm except... Soobin who's in his room. You could even hear roaring and groaning sounds from his room.
