The train Chorong and Naeun were in was about to pull into the next stop where the girls had to switch trains when Naeun's mobile phone sounded. Searching through her bag for the device, she raised an eyebrow in surprise after she took a glance at the caller ID.

No wonder Naeun was surprised when she picked up the call earlier.
