John, the pet dog, is good at escaping and the whole family goes out to look for him; Bunji and Fumi let John inside the house despite mom’s petition that he’s an outside dog. Guess what John brings for mom…; When John didn’t have a name, Bunji called him “Batman” and Fumi called him “Butterfly”. Despite what they called him, he always responded happily; John manages to escape again but this time, they can’t find him…
This is all for the sake of solving this case as quickly as we can. It can't be helped.
