Your and Jungkook's (who's been abroad for a year due to work) dog, Bam, keeps barking at the window.

You sigh and whistle, "whooow, boy, come here, Bam. Leave the bird alone."

Normally Bam retreats. But this time, he dashes to the door, scratching at it and barking, his tail wagging.

You raise an eyebrow and look curiously. What's got him so excited?

The key turns. Jungkook walks in.
