Soobin is an omega from a middle-class family. He's a medical student in his eighth semester, almost graduating. It was his dream to be a doctor; he'd dreamt of it since he was little. He specialized in general medicine, doing a little bit of everything. He was intelligent, but because of college and work, he didn't have much free time, sometimes only on weekends.

One day, it was almost 10 PM when Soobin was returning from his internship. He was exhausted when he heard his car make a strange noise, losing power. He pulled over to the side of the road, got out, and went to open the hood. He opened the hood and stared, trying to decipher everything. Soobin knew the signs of a body needing help, even without it fully showing, but he understood NOTHING about mechanics, barely the basics. He looked at the street; no one was passing by at that hour. He let out a long sigh and continued to look, brushing his blond hair away from his glasses.
