Happy Around! has been formed at last! 
It seems everything is going smoothly for their DJ activities... but suddenly the final exams stand in Rinku, Muni, and Rei's path.
To get them out of this crisis, Maho cooks curry...?!
When I see formulae,
my head spins uncontrollably.
عندما أرى المعادلات، يبدأ رأسي بالدوار
Wenn ich die Formeln sehe,
La cabeza me da vueltas cuando
veo fórmulas matemáticas.
Es ver las fórmulas
y empezar a marearme.
À chaque cours, j’ai l’impression
de tomber dans un gouffre sans fond.
Quando ho a che fare con le formule, mi gira la testa.
Quando vejo fórmulas,
minha cabeça começa a girar.
Когда вижу все эти формулы,
у меня начинает кружиться голова...
