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. 
I'm just touched by how much you've grown.
Ich bin nur gerührt,
wie erwachsen ihr schon seid!
Solo me conmovió su madurez.
Je suis juste ému
de vous voir si responsables.
Mi commuovo perché siete proprio bravi!
Só estou emocionado
por vocês terem crescido tanto.
Я просто тронут тем, какие вы взрослые.
