Gaelin stopped outside the classroom. “So it's true. You’re back.”

“I wondered when you’d turn up on my door.” The woman didn’t move from her spot at the piano.

Gaelin dumped her bag on the desk and approached the piano. “A little birdie told me that a blast from the past has swept into town.” Gaelin took a seat beside Oakland’s new music instructor. “The accomplished Han Sulli.” Gaelin touched a key and sighed, “You must want to be close to someone if you came all this way.”

“He’s a little tender,” Baekhyun informed Tanaka.

“Perhaps some hot chocolate?” Tanaka really didn’t like when any of the kids suffered.

“Hyung, how about something stronger?” Baekhyun teased and scurried off
