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. 
Don't you tell me to get some rest when I'm feelin' sick?
Wenn ich erkältet bin, sagst du immer,
ich soll Bettruhe halten!
Cuando yo me resfrío,
me dices que descanse, ¿no?
Quand j’ai un rhume,
tu me dis de rester au lit !
Mi dici sempre di riposarmi,
quando ho io l'influenza!
Não é você que fala para eu
descansar quando estou doente?!
