Mom, the air conditioner broke again this year.

Summer has arrived again this year. Hisae and her son, Kenichi, who had just finished their move, were wiped away sweat and trying their best to unlock the luggage. The two of them were the hot memories of their air conditioners breaking down last year...and the year before last and the summer. "The landlord has done the maintenance in this house so it's fine," Kotobuki said with confidence to Kenichi, but... However, as expected, the air conditioner broke.
