Mom Worries About Soundproofing

Synopsis

Yuzuhiko and Mikan cool off with the AC on, but Mom comes and turns it off, saying the weather's nice for fresh air. They hear arguing coming from the apartment below. The three go to the balcony to listen in, but Mom tells them to stop prying and come back inside. Then Mom worries: if they can hear the neighbors so clearly, doesn't that mean the neighbors can hear them too...
