Bruno had you and Giorno go on a mission together mostly because the others were too busy doing something else.. Whatever that means...

"Do you hear that noise?" Giorno stops walking abruptly making you smash into his back causing him to take a small tumble. Once hitting the floor, he lets out a grunt both of you tangled together on the somewhat warm ground the sunset still casting onto you and him

Giorno looks at you above him with his eyebrow raised he chuckles speaking in his calm yet sharp tone "Are you clumsy or just unbalanced?"
