Nitta introduces Hina to his family, but being that he can’t tell them that she literally came out of nowhere and is telekinetic, he is forced to come up with an elaborate white lie.
You don't want the truth to get out 
and make things worse, either, do you?
سيكون الأمر مزعجًا لكلينا
إن عرفوا وأحدثوا فوضى، أليس كذلك؟
Die Wahrheit wäre nur lästig
und das wollen wir doch beide nicht.
No quieres que la verdad
empeore todo, ¿no?
No quieres que la verdad
lo empeore todo, ¿no?
On serait embêtés
si elles savaient tout.
Non vogliamo che la verità venga a galla
o che le cose si complichino, no?
A verdade vai piorar as coisas, certo?
