Nobody talks about this one. A guy watching five-year-olds destroy themselves trying to tie their shoes becomes the most honest thing on screen about patience, failure, and why adults need to stop pretending they understand anything. The comedy isn't a joke, it's just what happens when you're actually paying attention to how small humans work.
A childcare worker in Tokyo who calls himself T-sensei looks after a class of kindergarteners, and the funny and touching moments of his days with them make up the story. The comedy, drama and slice-of-life series began with his real posts on Twitter, where he shared his work with young children starting in 2012 and drew a warm response from readers. Those posts became a seinen manga, written by T-sensei and illustrated by Yukue Takana, and this 14-episode ONA from 2017 adapts it.
