With their C-rank healer exam coming up, the girls are in a slump. Ria sends them on a training camp, where they hope to enrich their song with more life experience. But outside of Ria's watchful eye, jealousy begins seeping into the girls' relationships...
I've been jealous of you both the whole 
time we've been singing together.
كنتُ أغار منكما طوال غنائنا معاً
Ich war die ganze Zeit
neidisch auf euch,
Las he envidiado desde
que empezamos a cantar juntas.
He tenido celos de vosotras
desde que empezamos a cantar juntas.
Même si on a toujours chanté ensemble,
au fond, j’étais jalouse.
Io vi invidio fin da quando
abbiamo iniziato a cantare insieme.
Eu tive inveja de vocês o tempo todo
em que cantamos juntas.
Я завидовала вам всё то время,
что мы пели вместе.
