All done with their mock exams, the Himeno-Naoko-Mika trio spot
their pottery club advisor Mami by the train station and impulsively decide to tail her.
They pass through a forest, walk by a lake and finally reach a mountain.
Where exactly is Mami going?!
If you're always walking 
without seeing what's ahead,
إذا كنتِ تمشين دون رؤية
ما أمامك دوماً
Wenn man ohne Ziel
vor Augen voranschreitet,
Cuando sigues caminando
y no ves la meta,
Cuando avanzas y avanzas
pero no ves la meta,
Si on continue d’avancer
sans voir où l’on va,
Se cammini senza vedere cosa c'è più avanti,
Se você sempre anda
sem ver o que está adiante,
Если продолжать идти,
даже не видя цели,
