Like always, mom is taking the kids on the bike as she is huffing and puffing biking up a hill. As she is riding, she sees another homemaker speeding right past her on an electric bike; Mom noticed when she started to lecture Bunji, a beam came from his head and he wasn’t listening. Today, his beam also appears and he begins his communication; Out of nowhere, Fumi said that she wants her own room so she went to ask her dad; Bunji and Ma-kun have a falling out. Even though he is upset over the phone, Bunji asks Ma-kun over to play. They have a huge fight again so mom gives up on them.
And, that seemed to be a bad thing.
