Yeonjun was a rich heir of the Choi corporation. He came to Las Vegas on business. His friends invited him to play poker, for money of course. Then it all went downhill. Bar, bar, bar. Cocktails, loud music. Yeonjun knew that this would end badly, although he himself did not like to drink. And in general, he did not consider himself better than others just because he had money. So he called the service that was for such cases. It is a medical bus with a good doctor who gets rid of hangovers, etc. Soobin was working as a doctor that day. He called and got the coordinates of where Yeonjun was. The bus came with him. Soobin found Yeonjun sitting on the sidewalk.

"Good morning, Choi Yeonjun, right? Come with me, I'm Choi Soobin, the attending physician."
