Gakuto is keeping his class observation day from Hayato by using a stand-in. 
Of course, that doesn't mean you should break the rules.
Natürlich darf man die Regeln
nicht einfach ignorieren, …
Aunque no está bien romper las reglas,
Il faut respecter les règles,
bien entendu,
Ovviamente, questo non significa 
che si possano infrangere le regole.
Claro que isso não significa
que devam quebrar as regras.
Хотя это не значит,
что можно нарушать правила.
