It was their weekly shopping trip. The two had different opinions on the act but mutually agreed that it was a nice time to be together. Once they were in the store, they would spilt up and meet in the middle with their items from the list Yu usually created. Yosuke took his half and walked away. Looking at his list he noticed the little doodles and specific detailed items. Inwardly he just laughed at the little details. He knew why his half looked like this because a while back he completely forgot to grab an item even though it was printed right there.
As he continued walking around he decided to cause some mischief by grabbing odd items not on the list and seeing how long until his boyfriend noticed. After catching sight of Yu a little ways off, he reached out for the closest item and took it to their cart along with his list items. Always staying a step or two behind Yu, he would wait until the other was looking to add to their cart. This went on until they reached the aisle they usually met in. Yosuke watched as Yu finished up his list and check the cart to make sure they got everything. A questioning look on Yu's face began to form as he sorted through their groceries finding odd ball things that they didn't need. Yosuke stood off to the side silently giggling to himself as he watched.
Yu noticed this and spoke "Oh nice try mister, we'll see about next time where I follow you up and down every aisle watching you like a hawk."
"You wouldn't dare." he replied back. The two stared at each other and busted out laughing. Working together they put the items back and payed for their own stuff.
However, the next time they went to the store Yu held to his promise but it didn't last very long and they fell into their routine.
