Tsukishima and Kageyama continued their volleyball practice even after dinner. It was now 9 PM, and it was finally time to clean up and head home. The other members had already left for various reasons—studying for exams, practicing near their homes, or catching buses—leaving just the two of them to tidy up the gym. They went into the storage room together to put away the piled-up volleyballs. Just then, a strong gust of wind blew in, and the door suddenly slammed shut.

"Tsukishima. I think we're in trouble. This door won't open."

"Are you sure it's not just you being unable to open it?"

"It is not!" "No, it really won't open. Well, the security guard will do his rounds at 10:30, so let's just wait until then."

"Fine."

An awkward silence followed as the two remained trapped in the storage room. Kageyama continued practicing his volleyball moves even there, while Tsukishima, feeling exhausted, sat on a mat and fell asleep leaning against the wall. A few minutes later, Kageyama's body also gave in to the fatigue from practice, and he fell into a deep sleep as soon as he sat down and leaned against the wall. After some time had passed, Tsukishima woke up quietly. "Ugh... Urgh...!"

Tsukishima suddenly woke up to an intense urge to use the bathroom. He had felt a slight urge during practice, but since it wasn't a break and he was focused on training, he hadn't noticed it much. After practice, he had been so thirsty that he drank a whole bottle of water before cleaning up, and while he was asleep, the pressure had built up immensely.

"Hngh!"

'...I need... the bathroom....'
