Sunghoon was on the executive class train that was taking him to Seoul, when suddenly the girl sitting next to him leaned her head on his shoulder.

"Hey, are you okay?" Sunghoon asked worriedly. He shook her body. However, there was no response from the girl.

Sunghoon glanced forward slightly, and it turned out that the girl was asleep. He smiled.

"Okay, sleep well." He said while stroking her head. "You must be tired."
