Imagine...

Kai and Abby shopping - Abby is way more excited than Kai, who kinda just drags around and carries the bags.

~

Honestly, this would be their whole shopping dynamic

Especially when Abby goes shopping for clothes XD

She's like "Kai, let's go shopping! You have to come with me!" 

and Kai, knowing what's gonna happen, is like "Uuuuuugh do I have to?" 

And Abby practically drags him out of the house XD
