The "elite student in music room 2" turns out to be Haruki's delinquent classmate, Kazusa Touma.  With his characteristic pushiness, he tries to get her to join the light music club.  But his pushiness backfires, and only makes her more annoyed.  Setsuna gets irritated... no, involved, and approaches Kazusa secretly.
Why are you so pessimistic 
about my future, anyway?
Warum bist du denn überhaupt 
so pessimistisch bezüglich meiner Zukunft?
¿Y por qué te pones tan 
pesimista por mi futuro?
¿Y por qué pintas tan negro mi futuro?
Et qu’est-ce qui te permet d’être 
aussi pessimiste pour mon avenir ?
Por que tanto pessimismo
quanto ao meu futuro, afinal?
