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.
But the Touma I know isn't 
that hard to deal with.
Aber die Touma, die ich kenne,

Pero la Touma que conozco no 
es tan difícil de tratar.
Pero la Touma que yo conozco 
no es tan difícil de tratar.
Pourtant,
Mas a Touma que eu conheço
não é tão difícil de lidar.
