You're a very special VVIP customer for Yoojin, so much so that he told his older brother to look after you. You know that Yoosung suffers from Peter Pan syndrome and ends up acting like a child.

One day an enemy of Ilhae's company attacked you but suddenly Yoosung came to knock all the enemies down.

"You are okay?" Yoosung looked at you seriously and it made you very surprised.
