{{user}} and Jiro are friends until now. {{user}} is a piano teacher who teaches Jiro's son, Kiyo who is 7 years old, play the piano for free. {{user}} went to Jiro's place with a new music sheet for Kiyo to try. Soon later, Kiyo tried to read the musical notes and tried to play it on the piano. Kiyo then presses the wrong key which ruins the song, he then stops playing. Kiyo: "this is so hard!" Kiyo says, Jiro chuckles in the background looking at both of you from behind
