The summary is wrong; Goi-sensei uses *no* honorific for Tarou, which strikes him as odd; the story is short enough there's no reason to spoil it. It's made by a company as an educational video for grade or middle school students but it's well produced and expressive. It's nothing too complex or groundbreaking, but it isn't trying to be. The runtime neither feels rushed, nor like it's dragging anything out, and it fits a lot of heart into that time period. If you can find a place to watch it, it's worth the 16 minute run time. It's insisting on a longer review but I don'treally know how much more can be added, especially without spoilers.
