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'll... sleep it off...

Vou dormir... e melhorar...
Посплю, и мне полегчает.
