(Shinichi x Kaito) 'insert interesting title'

“Shin-chan I really got to goooo!!!” kaito whined, impatiently shifting from one foot to another.
Shinichi turned to face the man with a slightly exasperated expression, “My god, didn’t you go before we left?”
Kaito pouted, “Yea, but you try chugging a huge bottle of water and telling me you don’t have to go 15 minutes later.”
“Well then, go find the bathroom. This store isn’t very big.”
“But…”
“Go!”
“Tch, meany.”
So, kaito continued on straight, heading toward the large opening in the back wall of the store; Hanging above it was a huge cardboard sign with “restrooms” and an arrow, pointing to the right, scrawled across it. Shinichi veered off to the left, looking for the supplies they needed to buy.
Kaito watched him walk away for a bit before shaking his head of any indecent thoughts before he walked into what appeared to be some sort of storage room, or a loading dock.
It was dark, the only light coming from the actual store. Immediately to his right were a set of metal stairs that led up to a wooden platform. Next to, and covering a part of, the platform was a large blue tarp, spanning from the concrete floor to the plaster and metal ceiling and cutting off a large corner of the room. Peering into a tear in the tarp he could just barely make out boxes stacked upon one another. Seeing something moving behind the tarp he quickly backed away and continued on walking, though he was becoming more nervous with each step.
He soon spotted a sign a few more feet in, telling that the restrooms were on the right. He walked down a dark hall till he came across a rectangular room with one light on, bright and flickering, casting strange shadows about the room; The faint buzzing from the damaged light getting on his nerves.  He continued to look around the nearly empty room before he spotted a metal rack filled with white lab coats.  Looking a little further he found the end of the room to be dark. Extremely nervous now he started to back away from the room, nearly screaming when a loud noise echoed throughout the rooms. Abruptly he about faced and ran back into the main part of the store. He found Shinichi looking at the meats. Kaito startled some of the other late night shoppers as he called out to the man.
“SHIN-CHAN!!!”
“WHAT!?”
“It, it, it ….” kaito was now clinging to Shinichi.
“It what?”
“It felt like I was goanna get murdered!”
“Huh?”
“Save-A-lot bathrooms are scary.” Kaito whined. He was now determined to hold it until they got back home. After all staying alive was soooo much more important that reliving his bladder right away.
