Andou arrives at the club carrying a guitar to show off. After boasting about, he bets the guitar in a match with Chifuyu, but smashes the guitar in his own mistake. On his way home, he's so focused on his guitar that he forgets his bag in the clubroom and goes back to get it.

Espero que não pareça que estou
 me esforçando muito pra isso.
