In order to earn some money during Summer, Donghae decides to walk some of the neighbors' dogs or anybody's dogs for that matter. He happens to get thirteen regular customers. It would've been easy as pie except for one rebellious dog, good thing he's found himself a good helper...

“I’ll be walking dogs for the rest of the summer, want to help me?

I’d be really needing your help with Heenim.” 

“D-Donghae hyung!

Let’s walk the dogs again next summer okay?”
