Hayato catches a cold. Mikoto, Minato, and Gakuto are eager to care for Hayato and handle the household chores. Even when they run into the Kirishima family on their way to a trip, they keep Hayato's condition a secret, not wanting to worry them before their vacation. 
Just in case, I'm staying at your house today.
Zur Sicherheit übernachte ich heute bei euch.
Por si acaso,
hoy me quedaré con ustedes.
Je dormirai quand même chez vous,
au cas où.
Per sicurezza, però,
stanotte starò a casa vostra.
Por garantia, ficarei
na casa de vocês hoje.
На всякий случай я сегодня переночую
у вас. Займу гостиную.
