"This QUELL's song. Our song."

Izumi Shu, who once worked as part of a national idol unit, has been  busy lately promoting the drama he's starring in. Meanwhile, in order to catch up to their leader, Horimiya Eichi, Kuga Issei, and Kuga Ichiru, the other members of QUELL, devote themselves to their work and lessons.
Someday, our tears will return to the Earth
ذات يوم، ستعود دموعُنا إلى الأرض
Algún día,
nuestras lágrimas volverán a la tierra.
Algún día, nuestras lágrimas
volverán a la tierra.
Un giorno, le nostre lacrime torneranno sulla Terra
Algum dia nossas lágrimas
 voltarão para a terra
Однажды наши слёзы
вернутся на Землю...
