MidoFuri: "TOILET"(mah friend's)
In the wintercup stadium, after their match, Midorima had to go to the toilet. The kind that had more space and was separated from the restroom. After taking a dump, while he was about to flush it, Furihata suddenly came raging in because Midorima forgot to lock the door. "What the hell are you doing here?!" Midorima exclaimed angrily. "I'm sorry, I didn't know it was occupied!" Furihata cried and tried to go out but found out that the door was jammed, so the two of them got trapped inside.
Midorima was on the verge of exploding out of anger but decided to just wait until somebody saves them. Furihata told Midorima that he really needs to take a dump, so Midorima turned around to give him some privacy. Since the floor was quite slippery, Furihata suddenly slipped. Midorima turned around and saw that Furihata was crouched on the floor, his head inside the toilet.
When Furihata raised his head out of the toilet, he was already in tears because there was a few smears of dirt on his face which was Midorima's dump that he forgot to flush. Seeing that it was quite his fault for not flushing awhile ago, he helped Furihata sit up on the toilet, and since Furihata was still poopish and he couldn't take it anymore, he dumped in his pants, which startled Midorima and caused him to slip forward, his mouth landing on Furihata's open ones.
When somebody opened the door, they saw two men inside, one who had a pair of soiled pants and a foul odor around him, and one who was sulking while sitting on a lidded toilet bowl. From that moment on, Midorima decided to wait until he gets home if he ever needed to do his business on the toilet again.
