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 didn't think about it like that, I'm sorry.
Ich habe mir nicht genug
Gedanken gemacht, tut mir leid.
No puedo creer

Scusami, io non ci avevo pensato.
Eu não pensei por esse lado.
Peço desculpas.
Мне жаль, что я об
этом даже не подумал!
