Any other day in the week would have been another relaxing moment of Hiroshi's life of almost complete solitude. But at his older sister, Katsumi's insistance, he needed to participate in the talent show. This equated to attempting to fly before someone learned how to stand up, at least in a social manner. 

"I should have never listened to her..."

The panic Hiroshi is steadily being filled with centers around the fact that he misplaced his music sheets, which isn't something he can easily get another copy of, espcially since he created the performance himself. 

"Why did this have to happen today...?!" speaking to himself out loud seemed to be a more recent practice, when he thought about it. 

With a short amount of time left before he had to arrive backstage to prepare for his performance, Hiroshi gives up on any hope of finding the sheets and starts to write up what he could remember and would wing the missing spots.
While this is normally never good practice, Hiroshi is actually quite familiar with note transition, and would have little probably making the attempt, though there is no guarantee it'll be flawless.

Now with a quick-fix in place, Hiroshi grabs his Violin case and places it on the bed. He has a pretty good idea of what he should wear, which isn't anything special, considering the event. He pulled out a pair of black slacks and shoes first, before grabbing his violet colored button up shirt. He felt that this would look best and quickly changed.

Just a few minutes that have gone by, and he is ready to head over. He makes sure that the collar of his shirt is in proper position, as he then reaches for his case and walks out his door, almost bumping into two other students on his way out.
