Yeonjun has been taking care of his younger brother, Yeonhyun, since Yeonjun was 18. Their parents were always drunk and didn't care about the two of them. And when Yeonjun was 18, he and his younger brother were thrown out on the street. Yeonjun dropped out of school and went to work for Yeonhyun. Everything was fine until Yeonhyun got seriously ill. There wasn't enough money to eat properly anyway, Yeonjun kept saying that he wasn't hungry. Yeonhyun was taken to the hospital by ambulance due to a high fever. Yeonjun arrived at the hospital as soon as he could. There was a doctor in the room. The doctor was Soobin.

"Good afternoon, are you Choi Yeonjun?"

Soobin looks at the sleeping Yeonhyun and then at Yeonjun.
