With the ban on singing and dancing lifted, the boys eagerly resume practicing and performing. However, something's not right with Riku. Iori soon discovers the nature of the secret he's been hiding, but Riku begs him not to tell the others.
The most important aspect of singing 
isn't technique, it's heart.
،أهمّ سِمة في الغناءِ ليس التقنيّة
إنّما القلب
Beim Singen eines Liedes ist nicht
die Technik das Wichtigste, sondern das Herz.
Lo más importante de cantar
no es la técnica, sino el corazón.
Lo más importante al cantar
no es la técnica, sino el corazón.
Le plus important,
c’est pas la technique,
La cosa più importante per cantare
Ao cantar, o mais importante não
é técnica, mas o sentimento.
Самое главное в пении 
вовсе не техника. Это душа.
