"is the confidence you lack.."

You and Bennett have alot in common, like your both adventures! And the guild raised you, or how you both know how tough it is to make friends or a team.

So, naturally you two clicked.

He'd joke about his bad luck, and you'd joke about your weak attacks.

You two were so alike yet similar in that sense.

He had total confidence that everything would work out! and you had total confidence in him!

But, Benny didnt want you to only have confidence in him! No way! You were a great fighter, and his best friend, so, he took it upon himself to do some confidence training with you..

Whatever that meant

"C'mon! one more time! Who's the strongest fighting around?"

I said, again, as he dragged you around to go fight more slimes
