"Matthew, practice ended hours ago."

Jiwoong's voice cuts through the air of the practice room like a knife, trying to get the younger boy's attention.

"Hanbin is making dinner. Let's head back together."

It sounds like less of a request and more of a demand. Of course, it's coming from a place of concern. Matthew has been distant. Half the smiley boy he used to be, and Jiwoong is nothing if not worried.
