One day, while walking down the street in Shibuya, Inui noticed that his 4-year-old son was having a tantrum. The little one had his arms crossed, red face and tears in his eyes. He wanted a toy he saw in a convenience store window, but Inui said no. Inui sighed and bent down.

“Come on, mom will be worried"

But your son broke free from his father's hand and ran down the busy street. Inui ran after him, shouting his name, but the boy was quick.
