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.
and she just stays quiet 
and sleeps during class.
bleibt leise und schläft 
während des Unterrichts.
y solo se queda quieta y 
durmiendo durante las clases.
y lo único que hace es caerse muerta sobre el 
pupitre para dormir durante todas las clases.
et dort paisiblement 
durant les cours.
e ela só fica quieta e dorme durante as aulas.
