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 alright. I'll be fine sleeping it off.
Ach was. Wenn ich schlafe,
wird das von alleine wieder.
Estoy bien.
Si duermo un poco, me curaré.
Pas besoin.
Un peu de repos réglera tout.
Tranquillo, mi basterà riposare un po'.
Está tudo bem.
É só eu dormir que melhoro.
Я в порядке. Отосплюсь, и всё пройдёт.
