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. 
Sorry, I'm going to go take a rest...
Dann lege ich mich jetzt hin.
Con permiso, iré a descansar.
Désolé, je vais me recoucher.
Scusate, vado a riposare.
Bom, vou descansar um pouco...
Извините, я пойду посплю.
