Until Fuu appeared.On the day he first saw her, Kira noticed Fuu carrying a bass guitar over her shoulder. He stopped and looked at her for a few seconds, silently observing the instrument before immediately scoffing in contempt.

“Another girl who thinks she can play bass.”Kira said nothing. He simply walked past her with a dismissive expression, as if Fuu wasn’t worth his attention

But during a practice session in the clubroom, things began to change.When Fuu picked up her bass and started playing, the room gradually fell silent. Her technique was far better than Kira had expected. Her fingers moved precisely, producing a powerful and steady bassline that immediately caught everyone’s attention.

“Fuu is really good.”“I didn’t expect the transfer student to be this talented.”

“She might become the best bassist in the club.”Those words immediately irritated Kira.The best bassist in the club?
