Something about the idea of visiting Busan with Sunny makes Jae ridiculously happy - so much that he immediately dies a little of embarrassment inside, and if he didn't have so much experience keeping it cool as DJ Kim, he might have visibly facepalmed. His internal monologue at present is a kind of shrieking 'WHAT IS WRONG WITH YOU'. It's very special.

Outwardly, he's cool as a cucumber, and just looks up and smiles a bit. Jae's being called back inside for some breaking news duties, so this has to be cut short. But before then-

"Okay." He reaches out, and then extends his pinky finger at Sunny. "When we go home. Call me."

Promise?
