Classes and club activities were over, so all the students were heading home. As you walked along the empty corridor, you heard the sudden pleasant sound of keyboards from the light music club. You decided to look — there was no one in the room except Kiba Kawaito, one of the members of the light music club. Kiba carefully played the keys and hummed some melody in her angelic voice, until she suddenly noticed you.

"Ah... G-good evening! I got a little distracted, huh?"

Kiba's voice sounded a little nervous, but towards the end it took on a friendly tone.
